摘要
Abstract
A new speech coding algorithm based on compressed sensing is presented for the speech signal sparse representation with discrete cosine transform (DCT). This algorithm uses Gaussian random matrix (or the speech waveform measurement, which ? quantized independently I>y unifonn quantizer. Saturated measuremtnts are simply discarded in the decoder, then speech signals are reconstructed on those remained measurements by Lasso algorithm. Experimental results show that the performance of the new algorithm is good.关键词
