基于稀疏编码的TPM通信噪声抑制分析
Analysis of TPM Communication Noise Suppression Based on Sparse Coding
摘要
Abstract
The noise interference would bring tremendous influence on the Time-phase modulation system based on Independent Component Analysis( ICA) time domain filtering. This paper adopts sparse coding technology to suppress noise for time-phase modulation( TPM) communication signals. Firstly,sparse cod-ing method is adopted to encode with regard to observation signals and then the processed signals are com-pressed,thus these small argument-values are substituted by smaller or zero value and the noise is sup-pressed. The simulation shows that sparse coding method has suppressed noise better for the TPM commu-nication system and it can improve approximately 1 dB of system error performance.关键词
