Compressed Sensing of Noisy Speech Signal Based on Adaptive Basis Pursuit De-noising
摘要
Abstract
An adaptive basis pursuit de-noising method is proposed for compressed sensing of speech degraded by white Gaussian noise interference. This method adaptively selects the prime regularization parameter according to the SNR of original speech signal and enhancement is achieved as it is applied to noisy speech compression and reconstruction. The reconstructed speech signal via adaptive basis pursuit de-noising is evaluated by the objective and subjective evaluation. It is demonstrated that the performance of reconstructed speech based on adaptive basis pursuit de-noising is superior to basis pursuit,to low-SNR original speech signal.关键词
