宽带跳频信号的后验压缩采样技术研究
Research on posteriori compressive sampling using wideband frequency-hopping signals.
摘要
Abstract
Ultrahigh speed ADC (Analog to Digital Converter) sampling and fixed-frequency signal separation are long-standing problems for the wideband and non-cooperative frequency hopping signal in passive location. According to compressed sampling theory, analog information can be converted into digital information with far less than the Nyquist sample rate for some wideband signals are sparse in expression dictionary. However, sampling information that signal reconstruction needs increases sharply when multiple fixed-frequency signals exist, which brings tremendous complexity for AIC(Analog to Information Converter) module of distributed sensor system. Fixed-frequency interference AIC information of the target frequency band can be filtered out based on subspace projection. Simulation results show that the method is feasible.关键词
