[Dejun Zhang, Lei Miao, Jianfeng Xu, Fengyan Qi, Qing Zhang, Lixiong Li, Fuwei Ma, Yang Gao] CN Beijing Method, apparatus, and system for encoding and decoding signals are disclosed. The encoding method includes: converting a first-domain signal into a second-domain signal; performing Linear Prediction (LP) processing and Long-Term Prediction (LTP) processing for the second-domain signal; obtaining a long-term flag according to a decision criterion; obtaining a second-domain predictive signal according to the LP processing result and the LTP processing result when the long-term flag is a first flag; or obtaining a second-domain predictive signal according to the LP processing result when the long-term flag is a second flag; converting the second-domain predictive signal into a first-domain predictive signal, calculating a first-domain predictive residual signal; and outputting a bit stream that includes the first-domain predictive residual signal. Subsequent encoding or decoding process is performed adaptively according to the long-term flag; and it is not always necessary to consider the LTP processing result, thus improving the compression performance of codec.

[Fengyan Qi, Dejun Zhang, Lei Miao, Jianfeng Xu, Herve Marcel Taddei, Qing Zhang, Yang Gao] A pitch detection method and apparatus are disclosed. The method includes: performing pitch detection on an input signal in a signal domain, and obtaining a candidate pitch; performing linear prediction (LP) on the input signal, and obtaining an LP residual signal; setting a candidate pitch range that includes the candidate pitch; searching the candidate pitch range for the LP residual signal, and obtaining a selected pitch.

[Dejun Zhang, Jianfeng Xu, Lei Miao, Fengyan Qi, Qing Zhang, Herve Marcel Taddei, Lixiong Li, Fuwei Ma, Yang Gao] CN Shenzhen The present invention relates to a method and apparatus for pitch search. One method includes: obtaining a characteristic function value of a residual signal, where the residual signal is a result of removing a Long-Term Prediction (LTP) contribution signal from input speech signals; and obtaining a pitch according to the characteristic function value of the residual signal.
