摘要： PROBLEM TO BE SOLVED: To provide a communication device that is switchable to a communication frequency with three channels or more by preventing the response time of a system from becoming longer without increasing the number of signal lines for channel control.SOLUTION: A signal processing unit 10 designates a channel to be used for communication among channels ch1 and ch2, and outputs a high-level signal or low-level signal to a signal line 32 depending on the designated channel. A control circuit 22 operates a reception circuit 21 by the ch1 or ch2 depending on whether the signal of the signal line 32 is the high-level signal or low-level signal. If the signal processing unit 10 has detected a channel on which communication is difficult to establish, it transmits an instruction signal to instruct shift to a frequency setting mode and information on a communication frequency to be newly set to a tuner 20. If the tuner 20 has received the instruction signal, it shifts to the frequency setting mode and re-writes a memory 23 to the new communication frequency.

摘要： A BT receiver RF front end receives RF energy in a sequence of BT scan windows. Throughout a scan window, the front end is tuned to one hop frequency. Before and after the window the front end is in a disabled state. A WLAN energy detector processes an output of the front end during the window and determines whether more than a predetermined amount of RF energy was received onto the front end during the window. A BT baseband processor attempts to demodulate the output of the front end. If the WLAN energy detector determines that the predetermined amount of RF energy was received and if a BT signal could not be demodulated, then a WLAN wake-up signal is asserted, thereby causing a WLAN transceiver to be powered up to receive WLAN signals. BT scan intervals are varied in duration to facilitate a BT scan window overlapping a WLAN beacon.

摘要： PROBLEM TO BE SOLVED: To provide a technique to make it possible to reliably receive paging data with saving power. SOLUTION: A mobile communication device is intended to intermittently perform receiving operations at reception timing of intermittent-receiving cycles synchronized with timing of paging from a base station. The device includes: a measuring means for measuring a reception sensitivity of electrical waves transmitted from the base station; and an intermittent-receiving control means for regarding a time from transmission of paging data by the base station to retransmission of the paging data as a retransmission time if the reception sensitivity measured by the measuring means is greater than a predetermined value, to skip the reception operation in the reception timing at a skip cycle determined based on the retransmission time and the intermittent-reception cycle.

摘要： PROBLEM TO BE SOLVED: To easily prevent interference with other radio transmission systems though in a simple configuration. SOLUTION: After frame synchronization is completed, a control part 1 decides whether or not the system code SysID of received radio signals matches a system code SysID stored (registered) in a nonvolatile memory. When the system code SysID does not match, a radio transmission part 2 is immediately stopped, the reception of radio signals is stopped, and the count of an intermittent reception interval is restarted. That is, even when another system using the radio signal of the same frequency is present nearby and the radio signal of the another system is received, since the system code SysID does not match, it is discriminated that the radio signal is the one of the another system and the interference is prevented. Also, since the system code SysID and the identification code of radio equipment TR1 which is a master station are the same, the configuration is simplified. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：通过简单的配置，可以容易地防止对其他无线电传输系统的干扰。解决方案：帧同步完成后，控制部分1判定所接收的无线电信号的系统码SysID是否与非易失性存储器中存储（注册）的系统码SysID相匹配。当系统码SysID不匹配时，无线发送部分2立即停止，停止接收无线电信号，重新开始间歇接收间隔的计数。也就是说，即使在使用具有相同频率的无线电信号的另一个系统在附近存在并且接收到另一个系统的无线电信号的情况下，由于系统码SysID不匹配，所以鉴别出无线电信号是另一个系统和干扰被阻止。此外，由于系统码SysID和作为主站的无线电设备TR1的识别码相同，因此简化了配置。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce the possibility of timeout in synchronization processing while shortening a synchronization section of a radio signal.SOLUTION: A reception control part 11 of an embodiment makes a radio reception part 10 stop until second standby time ΔTstop 2 passes, where the second standby time is shorter than first standby time ΔTstop 1 (>ΔTstop 2) that is standby time in the case of receiving no electric wave, when synchronization of a radio signal is not achieved after the electric wave is received. Thereby, the possibility that timeout occurs in synchronization processing of the radio reception part 10 on a synchronization section of a desired wave is reduced as compared with the case such as a conventional example in which standby time when synchronization processing is timed out is equal to the standby time ΔTstop 1 when it is determined in the electric wave check that no electric wave exists. As a result, the possibility of the timeout in the synchronization processing can be reduced while shortening the synchronization section of the radio signal.
摘要翻译：要解决的问题：为了减少同步处理中的超时的可能性，同时缩短无线电信号的同步部分。解决方案：实施例的接收控制部分11使无线电接收部分10停止，直到第二待机时间ΔTstop2通过，其中第二待机时间短于待机时间的第一待机时间ΔTstop1（>ΔTstop2）在不接收电波的情况下，在接收到电波之后不能实现无线电信号的同步。因此，与期望波的同步部分上的无线电接收部分10的同步处理中发生超时的可能性相比，将诸如同步处理超时的待机时间等于在电波检测中确定没有电波存在时的待机时间ΔTstop1。结果，可缩小同步处理中的超时的可能性，同时缩短无线信号的同步部分。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus to compute the combiner coefficients for wireless communication systems for a space-time solution.SOLUTION: One embodiment trains the weights on a signal known a priori that is time multiplexed with other signals, such as a pilot signal in a High Data Rate, HDR, system, where the signal is transmitted at full power. A Minimizing Mean Square Error, MMSE, approach is applied allowing weight combining on a per path basis. The weights are calculated as a function of a noise correlation matrix and spatial signature per path. The noise correlation matrix is determined from an autocorrelation matrix of the received signal. The MMSE approach is applied to a non-time gated pilot signal.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption by shortening the rising time in MBMS standby without damaging the check performance of MICH. SOLUTION: For four DRX reception periods within a modification period, the reception check of the MICH is performed in the order from the leading DRX reception period, and when it is determined that reception quality Ec/Io at this time exceeds Sintra which is a threshold though call termination is not detected, it is discriminated that the MICH reception check result is highly reliable, and the succeeding DRX reception periods within the modification period are set to a sleep state. On the other hand, when the reception quality Ec/Io does not exceed Sintra, it is discriminated that the MICH reception check result is not reliable, and the reception check of the MICH is repeated in the succeeding DRX reception periods as well until the Ec/Io exceeds Sintra.

摘要： PROBLEM TO BE SOLVED: To provide a radio relay device capable of estimating radio wave intensity from a radio base station to suspend a communication function with a radio terminal according to the radio wave field intensity.SOLUTION: A radio relay device includes: a base station controller 24 for acquiring first electric field intensity of a radio wave from a terminal communication unit 32 at a base station communication unit 22, and for acquiring transmission power information of the terminal communication unit 32; and a terminal controller 34. From the base station communication unit 22, the base station controller 24 acquires second electric field intensity of a radio wave from the radio base station at the base station communication unit 22. Based on the first electric field intensity and the transmission power information, the terminal controller 34 calculates a propagation loss, and from the second electric field intensity and the propagation loss, estimates third electric field intensity of the radio wave from the radio base station at the terminal communication unit 32, and suspends the operation of the terminal communication unit 32 if the third electric field intensity is greater than a predetermined threshold.
