利用多通道、低速率采样信号重构完整宽带信号的稳健方法
Robust Method of Reconfiguring Complete Broadband Signal by Multi-channel and Low Rate Sampling Signal
摘要
Abstract
Sampling broadband signal directly requires a high sampling rate of A/D converter, which leads to a reduction of the sampling accuracy and is difficult to be realized. An idea that performing a multi-channel and low rate sampling with broadband analog signal is introduced, a new method of utilizing adaptive beamforming technique to recover complete bandwidth of the broadband signal is proposed. Application of this method can implement both low rate sampling and high accuracy) in addition, it is robust to channel delay and other errors. The processing result of the simulated data verifies the effectiveness of this method.关键词
