Signal processing method and device
2012
The invention provides at least one signal processing method and device, which are suitable for a communication device. One signal processing device comprises a rate de-matching module, a decoder, a signal quality generation module and a control module. The rate de-matching module is used for carrying out rate de-matching module on a control signal obtained after demodulation in order to obtain a rate de-matching signal; the decoder is used for decoding the rate de-matching signal to obtain a decoding signal; the signal quality generation module is used for generating at least one signal quality indicator according to the control signal and the rate de-matching signal, the at least one signal quality indicator includes a similarity indicator obtained by executing similarity calculation on the control signal and the rate de-matching signal by the signal quality generation module; the control module is used for determining and controlling whether to stop decoding operation on the rate de-matching signal of the current control signal according to the at least one signal quality indicator. The method and the device have the advantages that the number of decoding operations can be reduced and the signal detection efficiency can be improved.
