Patent ID: 8170162

Claim:
A reception device that performs diversity reception, the reception device comprising: a plurality of reception processing units, each reception processing unit of the plurality of reception processing units being operable to receive a reception signal via an antenna corresponding to one reception processing unit of the plurality of reception processing units, and to demodulate the reception signal; a first combining unit operable to (i) receive first output signals from the plurality of reception processing units, (ii) perform diversity combining on all of the received first output signals, so as to obtain a combined signal, (iii) perform hard decision on the combined signal according to a transmission code position, and (iv) output a hard decision result to each reception processing unit of the plurality of reception processing units; and a second combining unit operable to (i) receive second output signals from the plurality of reception processing units, and (ii) perform diversity combining on the second output signals, wherein each reception processing unit of the plurality of reception processing units includes: a first reception signal processing unit that generates one first output signal of the first output signals by demodulating the received reception signal, and outputs the one first output signal to the first combining unit; and a second reception signal processing unit that (i) generates one second output signal of the second output signals by demodulating the received reception signal using the combined signal received from the first combining unit, and (ii) outputs the one second output signal to the second combining unit.
