Implementation of G.723.1 Dual Rate Codec Algorithm in DSP
Quan Zheng · Computer Engineering and Applications Journal · 2006
In the article,the G.723.1 dual rate codec algorithm and the features of LSI403LP(LSI Logic) are introduced at first.The G.723.1 algorithm is then optimized based on the fact that the C code of the Recommendation is deeply analyzed.Then this algorithm is realized on LSI403LP.The results indicate that the lower algorithm time complexity and satisfied synthetic speech quality are received.
