The invention is concerned with the signal detection method, including: the feedback signal parallel passes each feedback signal correlator; gets the feedback signal combination according to the output of each feedback signal correlator by gridding chart, the gridding chart is all feedback signal combination. The invention is also concerned with the signal detection equipment, it is: gets the feedback signal combination according to the gridding chart and the feedback signal correlator output by the known feedback signal forms rules and gridding table, because the gridding table is the combination of all feedback signal and without impossible feedback signal, reduces the occupied storage quantity when detecting feedback, improves the effect of the detection feedback signal.
Description
A method and device for obtaining a feedback signal technical field The present invention relates to a communication technology, in particular to a method and device for acquiring a feedback signal. Background technique In the WCDMA (Wideband Code Division Multiple Access) system, the use of HARQ (Hybrid Automatic Repeat Request) technology can effectively improve the throughput of packet data, that is, for the data sent by the sender, the receiver will, according to the receiving situation, Feedback ACK (acknowledgement response), NACK (non-acknowledgement response) or DTX (no response) signal to the sender respectively. Among them, ACK indicates that the data is received correctly; NACK indicates that the data is received incorrectly; DTX indicates that the data has not been received. The sender determines whether to retransmit by detecting the feedback signal from the receiver. In order for the sender to distinguish ACK, NACK and DTX signals, the receiver needs a lar...
