摘要： SFTD coding section 10 adjusts a sequence of frequency arrangement and phases of transmit data digital symbols in a time series and thus generates at least two transmit signals. The transmit signals are transformed into parallel signals in serial/parallel transform sections 11 and 12, and subsequently transformed into OFDM signals in IDFT sections 13 and 14 and parallel/serial transform sections 15 and 16, respectively. In this way, by using the multicarrier transmission scheme, it is made possible to encode on the frequency axis signals conventionally encoded only on the time axis, and it is thus possible to decrease the processing delay while obtaining the same diversity effect as in the STTD transmit diversity scheme.
摘要翻译： SFTD编码部分10按照时间顺序调整发送数据数字符号的频率排列和相位序列，并因此产生至少两个发送信号。发送信号在串行/并行变换部分11和12中被变换为并行信号，并且随后被分别变换成IDFT部分13和14以及并行/串行变换部分15和16中的OFDM信号。以这种方式，通过使用多载波传输方案，可以在频率轴上编码仅在时间轴上传统编码的信号，并且因此可以减少处理延迟，同时获得与STTD中相同的分集效果发射分集方案。

摘要： Session monitoring section 104 notifies threshold control section 106 of the session time and interference time together with information that a call has been terminated and notifies threshold control section 106 of information that a forced disconnection has occurred. Channel assignment section 105 notifies threshold control section 106 of information that a call loss has occurred. Threshold control section 106 adaptively changes a decision threshold according to an interference rate, occurrence of a forced disconnection or occurrence of a call loss. Channel assignment section 105 then assigns channels based on a result of a comparison between the decision threshold controlled by threshold control section 106 and the CIR value of the uplink.

摘要： The communication terminal apparatus measures reception quality and reports the measurement result to the base station apparatus, and the base station apparatus switches the transmission rate based on the reported result of the reception quality. In this way, the transmission rate is switched starting at the point in time at which the reception quality of the communication terminal apparatus deteriorates. Furthermore, the transmission rate is switched so that the amount of interference with others is within the allowable range according to the channel condition between the communication terminal apparatus and base station apparatus.

摘要： Based on the determination of a transmission destination determination section 106, a data selector 151 selects only transmit data for the corresponding communication terminal apparatus. An adaptive modulation section 153 modulates the output signal from the data selector 151 using the modulation method indicated by a modulation method determination section 152. A spreading section 154 spreads the output signal from the adaptive modulation section 153 and outputs the resulting signal to a code multiplexer 158. A dedicated pilot signal generator 155 generates a dedicated pilot signal. A modulation section 156 modulates the dedicated pilot signal. A spreading section 157 spreads the output signal from the modulation section 156 and outputs the resulting signal to the code multiplexer 158. The code multiplexer 158 performs code multiplexing of the output signal from the adaptive spreading section 154 and the output signal from the spreading section 157 and outputs the resulting signal to a time multiplexer 162. By this means it is possible to maintain data-part reception quality when performing high-speed downlink packet transmission even when phase changes are sudden.

摘要： Code multiplexing section 102 multiplexes spread data output from spreading sections 101-1 to 101-n to generate code-multiplexed data. Reference data generating section 103 generates redundant data with the constant transmit power and with no information contained therein. Data adding section 105 adds the redundant data to the code-multiplexed data. Variable amplifying section 108 variably amplifies the transmit power of the code-multiplexed data and of the redundant data to obtain transmit output data. Difference value calculating section 112 calculates a difference value between a target amplitude value based on the redundant data and the redundant data portion of the transmit output data. Gain control section 113 generates based on the difference value a gain control signal to control the gain of variable amplifying section 108. It is thereby possible to perform the gain compensation with a small calculation amount and with high accuracy.

摘要： A desired wave power detection section 10 detects desired wave power from a received signal. On the other hand, an interference wave power detection section 11 detects interference wave power from the received signal. Interference wave power before and after in time receives averaging processing over a long interval in an averaging section 12, and receives averaging processing over a short interval in an averaging section 13. A differencing device 124 obtains a difference between an averaged value over the long interval and an averaged value over the short interval. A selection section 16 selects the averaged value of the short interval in the case where the obtained difference is larger than a prescribed threshold value, and selects the averaged value of the long interval in the case where the obtained difference is smaller than the prescribed threshold value. An SIR calculation section 17 obtains a ratio of the averaged value selected by the selection section 16 to the desired wave power detected by the desired wave power detection section 10.
