Patent ID: 6915465

Claim:
A received-signal combining method of transmitting signals, based on a signal having undergone error-correction coding and transmitted from a radio-transmitting station, to a receiving station from a plurality of radio-receiving stations, and generating a reception-information sequence based on the thus-transmitted signals, by said receiving station, comprising the steps of: a) each radio-receiving station rendering error-correction decoding and error detection processing on the signal transmitted from said radio-transmitting station, and transmitting the error-correction-decoding result to said receiving station when no error is detected by the error detection processing; and b) said receiving station combining the received error-correction-decoding results according to a first algorithm when receiving the error-correction-decoding results from any radio-receiving stations, and, thus, generating the reception-information sequence, wherein each radio-receiving station transmits the signal before undergoing the error-correction decoding processing when an error is detected in the error detection processing, and when receiving the signals before undergoing the error-correction decoding processing from all the radio-receiving stations, said receiving station combines the thus-received signals according to a second algorithm, then, renders error-correction decoding processing thereon, and, thus, generates the reception-information sequence.
