Abstract
It is required that an ADC for sampling broadband signal directly has high sampling rate, and this will make the sampling accuracy decrease and difficult to be realized. This paper introduces an idea that using multi-channel and low rate ADCs performs sampling broadband signal, then presents a novel method of utilizing adaptive beam forming technique to recover complete bandwidth of the broadband signal. 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 result of processing the simulated data has verified the effectiveness of this method.
