<P>PROBLEM TO BE SOLVED: To provide a single carrier receiver apparatus which can attain radio transmission which is hard to break off following a propagation channel which fluctuates at high speed. <P>SOLUTION: A block synchronization part 11 calculates synchronous point information by correlation processing between unique word symbols arranged before and after a data symbol and unique word symbols delayed for N symbols to calculate block-synchronized received signals. A noise power detection part 12 performs phase rotation of the block-synchronized received signals according to the synchronous point information to delay it for N symbols, and detects noise power for P symbols in the latter half in the unique word symbols. A frequency domain synthesis part 13 synthesizes a plurality of received signals in a frequency domain using the plurality of received signals, channel information and the noise power, and returns them to signals of a time domain. Thus, channel estimation is performed per one block, and diversity synthesis of the maximum ratio synthesis type according to SNR is performed to the plurality of received signals using the unique word symbols. <P>COPYRIGHT: (C)2011,JPO&INPIT |
