Abstract:
1. A method for processing speech signal, comprising: receiving an encoded speech signal sent by a base station, wherein the encoded speech signal comprises a first substream, a second substream, and a third substream, and the first substream is attached with a cyclic redundancy check (CRC); performing decoding processing on the first substream, the second substream, and the third substream by adopting a decoding algorithm to acquire decoding results of the first substream, the second substream, and the third substream, wherein a decoding algorithm that is based on an auxiliary decision of the CRC is adopted to perform decoding processing on the first substream and a decoded result of the first substream comprises a decoded bit stream and a CRC result; and performing decoding processing on an adaptive muti-rate (AMR) speech signal according to the decoded bit stream and the CRC result of the first substream, decoded results of the second substream and the third substream; and reducing a target block error ratio of an outer-loop power control and performing an inner-loop power control according to a reduced target signal-noise ratio and a measured signal-noise ratio, wherein the reduced target signal-noise ratio is acquired according to the reduced target block error ratio.
