摘要： A radio communication apparatus, base station apparatus and communication terminal apparatus capable of predicting an accurate transmission rate before starting data communications to know download time and the like. In the apparatus, a packet CH demodulation section (103) demodulates received packet data. A pilot CH demodulation section (104) demodulates a received signal of a pilot channel. A reception state measuring section (105) measures the SIR from the received signal of the pilot channel. A transmission rate candidate selecting section (106) stores a calculation expression that associates CQI with SIR, and selects CQI by the calculation expression using the measured SIR. A transmission rate predicting section (108) averages selected CQI for a predetermined time to output a transmission rate prediction value. A transmission rate prediction control section (110) outputs information of the transmission rate prediction value to a display section (111) when detecting a key input. The display section (111) displays the transmission rate prediction value on a liquid crystal screen.

摘要： An interference cancellation apparatus and method may remove interference from a directional array combined signal that is received by an array antenna and array combined on a directivity-by-directivity basis. The apparatus and method input a plurality of array combined signals subjected to array combining on a directivity-by-directivity basis to select an array-combined signal corresponding to a path. A correlation value is detected between the selected array combined signal and a spread code. Detected correlation values are combined to generate a combined value, and the combined value is used to generate a temporarily determined value. The temporarily determined value is re-spread to generate a re-spread signal, and re-spread signals are sorted for every directivity, on a per path basis. The re-spread signals sorted for every directivity are then added to generate a replica signal.

摘要： The base station apparatus compresses one-frame information of a broadcast channel to blocks of ½ of one frame or less and repeatedly sends this block in a one-frame time. The mobile station apparatus decodes the received signal in block units or added block units to carry out error detection. The mobile station apparatus receives and adds up the next block in the case that the error rate exceeds a threshold. The mobile station apparatus repeats this until the error rate falls below the threshold. When the error rate falls below the threshold, the mobile station apparatus stops reception of broadcast channel signals and uses the rest of time until a one-frame time elapses to monitor carrier information of a different mobile communication system for handover.

摘要： A base station transmits, in addition to a pilot channel, signals which are multiplexed with pilot symbols inserted in the respective signals in communication channels. As the transmission of the pilot channel as a reference signal for coherent detection is unnecessary with high power so as to attain high reliability, the pilot channel can be transmitted with low power by means of weight in comparison with the communication channel, so that interference with the communication channel of any other station is reduced. Moreover, accurate coherent detection can be made from the pilot symbol inserted in the communication channel on the mobile station side.

摘要： In the CDMA Radio Multiplex Transmission, transfer function of line is inferred by using common pilot signal and synchronous detection is performed accordingly. The transmitting end transmits by periodically inserting pilot symbols into one channel only of multiplexed channels. The receiving end infers line condition (transfer function) from the received pilot symbols and, on the basis of the information thus obtained, performs synchronous detection of each channel multiplexed.

摘要： When a power supply of a mobile radio apparatus is turned on, a power supply change-over switch of a power supply control unit is changed over to the side of a pager unit to turn on only a power supply of the pager unit, so that a pager network which does not require position registration is utilized to perform intermittent receiving operation with low power consumption. When there is an incoming call to the pager unit, a CPU of the power supply control unit receives an incoming control signal from a pager decoding circuit and changes over the power supply change-over switch to the side of a radio-telephone line terminal unit to turn on the radio telephone line terminal unit and turn off the pager unit. The CPU sends a control signal to a timing control circuit of the radio-telephone line terminal unit so that the position registration is performed by utilizing a mobile radio network and an operation mode of the mobile radio apparatus proceeds to a usual talking mode. After a pager calling has been performed in a calling side, the mobile radio apparatus is called by the portable telephone number and talking is then is made. When the talking has been finished, the CPU receives a control signal from the timing control circuit and changes over the power supply change-over switch to the side of the pager unit again to turn on the pager unit to enter a waiting state for reception.
