摘要： A wireless communication apparatus capable of enhancing the transmission efficiency, while maintaining a good BER characteristic. In this apparatus, a setting part (13) sets, based on the maximum delay amount of a delayed wave and also based on the expansion of impulse response of FDE, an FFT part (14) to establish an FFT section of Nc symbol, and also sets a selecting part (17) to establish a selection section of Nc−2M−Δ symbol that is shorter than the FFT section. The setting part (13) also sets the start points of FFT and selection sections established at this time for such timings that they are shifted by Nc−2M−Δ symbol from the start points of the FFT and selection sections previously established. It should be noted that the maximum delay amount of the delayed wave is Δ symbol, the expansion of impulse response of FDE is plus/minus M symbols, and the symbol block length is Nc.

摘要： Provided is a wireless communication device which can improve the notification accuracy of the channel state information (CSI) without straining the feedback circuit. In this device, a channel estimator (105) uses a pilot signal input from a wireless receiver (102) to estimate the channel and obtain a plurality of path gains in each of a plurality of delay periods. Then, the channel estimator (105) outputs the plurality of path gains to a quantizer (107). The quantizer (107) quantizes the plurality of path gains in the number of notification bits corresponding to each of the plurality of delay periods based on the correspondence of the delay period and the number of notification bits input from a setting unit (106).

摘要： Provided is a radio communication device capable of preventing lowering of the frequency diversity effect when using the CDD (Cyclic Delay Diversity) in combination with the frequency diversity technique in a multi-carrier communication. In the radio communication device (100), a repetition unit (103) repeats each symbol to generate the same symbol, an S/P unit (104) converts a symbol string inputted in series from the repetition unit (103) into a parallel string, and an arrangement unit (105) arranges a plurality of symbols inputted in parallel to any of a plurality of sub-carriers constituting the OFDM symbol. Here, the arrangement unit (105) correlates a plurality of the same symbols generated by repetition to a cyclic delay in the CDD and arranges them to any of the sub-carries constituting each of the OFDM symbols at a sub-carrier interval based on the number of antennas and the delay amount of the CDD transmission.

摘要： In order to reduce interference between cells through hopping and use frequencies in a good propagation situation, a scheduler section 102 carries out scheduling for determining to which user data should be sent using CQI from each communication terminal apparatus, selects a user signal to be sent in the next frame and determines in which subcarrier block the data should be sent. An MCS decision section 103 selects a modulation scheme and coding method from the CQI of the selected user signal. A subcarrier block selection section 110 selects a subcarrier block instructed by the scheduler section 102 for each user signal. For the respective subcarrier blocks, FH sequence selection sections 111-1 to 111-n select hopping patterns. A subcarrier mapping section 112 maps the user signal and control data to subcarriers according to the selected hopping pattern.

摘要： Provided is a radio communication base station device capable of suppressing degradation of a signal error ratio characteristic for a mobile station in the vicinity of the cell center when a plurality of signals whose transmission power is to be controlled are frequency-multiplexed or code-multiplexed. In the device (100), a classification unit (118) classifies a plurality of DPCCH according to the MCS of SCCH into a plurality of groups based on the transmission power intensity. A spread code is allocated for each DPCCH according to the classification result. A spread code for spreading a response signal (ACK signal/NACK signal) is instructed to spread units (103-1 to 103-n). The spread units (103-1 to 103-n) spread the response signal by the spread code instructed from the classification unit (118). According to the classification result in the classification unit (118), a mapping unit (104) maps the response signal after the spread to one of the subcarriers constituting the OFDM symbol.

摘要： In maximum delay time setting section 106, a delay time width W′ used for cancelling the interference is set using the delay profile. In the present embodiment, delay spread is calculated and a delay wave included in the delay spread is set as W′. First, the delay spread is calculated in delay spread calculating section 1061 of maximum delay time setting section 106. That is to say, the standard deviation of the delay profile is calculated. The calculated delay spread is outputted to maximum delay time determining section 1062. The maximum delay time (window width) W′ is determined in maximum delay time determining section 1062 based on the delay spread. Therefore, the delay wave included in the maximum delay time which is determined by such a way is set to be an object of interference cancellation in joint detection. Thus, besides interference cancellation performance, optimization of calculation scale can be planned without losing performance of RAKE combining.
