摘要： A delay device 102 sends reception signals to a subtraction device 113 after delaying it by a predetermined time. Matched filters 103-1˜103-N perform despreading operation of the reception signals. RAKE-combining devices 104-1˜104-N perform RAKE-combining operation of the signals after the despreading operation. Discrimination devices 105-1˜105-N perform hard decision of the signals after the RAKE-combining operation. A decision value buffer 107 stores the signals after the hard decision. Likelihood calculation devices 106-1˜106-N calculate likelihood of all the symbols. A likelihood buffer 108 stores calculated likelihood. A controlling part 110 controls a switch 109. A ranking decision device 111 decides a ranking based on the likelihood. A re-spreading device 112 performs re-spreading operation of a symbol with the highest likelihood ranking. And a subtraction device 113 subtracts the re-spreading result from the delayed reception signals.

摘要： Of systematic bits (S) and parity bits (P1, P2) generated by coding (coding rate R=1/3) transmission bits, subcarriers to which parity bits are mapped are designated as candidates for transmission cancellation and subcarriers not to be transmitted are selected from among those candidates. When this selection is made, a selection pattern which corresponds to minimum peak power of an OFDM symbol is used based on values of parity bits and phase relationship between subcarriers.

摘要： The transmission/reception apparatus of the present invention, on its transmitting side, performs sweeping by sweep circuit 106 that changes with time the central frequency of a modulated signal according to a predetermined sweep pattern of frequency change controller 107 and then transmits the signal. On its receiving side, it detects a received signal while sweeping the central frequency with the same sweep pattern as that on the transmitting side created by frequency change controller 112. In this way, signals are transmitted correctly.

摘要： The present invention carries out transmission/reception of broadcast channels using only the last downlink slot of subframes using signals having a TDMA structure according to a CDMA/TDD system, and thus flexibly handles various services and avoids problems of interference in self-operated services in particular. The base station communication apparatus repeatedly transmits information contained in broadcast channels by the number of times corresponding to the time-sharing number and appropriately allots uplink and downlink slots, thus making the most of the features of uplink open-loop transmission power control and base station transmission diversity.

摘要： A synchronization equipment performs correlation processing between a first known pattern included in a received signal and a second known pattern, and detects reception timing of the received signal. A correlation value computing portion computes a correlation value between the first known pattern and the second known pattern at every reception time. A reception timing detection portion compares the computed related value with a predetermined threshold value, determines the reception time when the correlation value becomes larger than the threshold value to be the reception timing of a received signal, and, after this determination, suspends the comparison between the correlation value and the threshold value, and holds the reception time determined to be the reception timing.
