Joint detection and soft decision decoding-based signal receiving method

The present invention proposes a signal reception and joint detection method based on soft-decision decoding, the method comprising: a joint detection on the received signal; B based on the result of joint detection calculating reliability information of the received signal; C based. reliable information on the received signal soft-decision decoding. The present invention effectively combines the combined soft-decision decoding and detection of the two technologies, we can further improve the performance of communication systems.
