<p>PROBLEM TO BE SOLVED: To improve accuracy in error correction when applying the result of joint detection demodulation to an error correction/decoding system. SOLUTION: Path selection sections 105a to 105n cut a signal other than an effective path such as noise from a delay profile, outputs a channel estimation value obtained by selecting only the effective path to a JD demodulation section 106, and outputs the reception level of the effective path to multipliers 108a to 108n. The JD demodulation section 106 performs joint detection operation, and multiplies a matrix operation result by a reception signal outputted from delay equipment 10. A distribution section 107 distributes soft decision data of each user for each user. Error correction/demodulation sections 109a to 109n allow the soft decision data to be subjected to hard decision to obtain the demodulation data of each user.</p> |
