Time and frequency domain receiver of UWB signal based on compressive

In order to reduce the request of ADC resource and improve the performance of interference suppression of UWB receiver, we proposed a new UWB receiver named time and frequency domain receiver of UWB signal based on compressive sampling. The received signal completed compressive sampling by convolute a random filter and sampled at a low sample rate. Signal reconstruction completed by Orthogonal Matching Pursuit algorithm in time and frequency domain respectively. The computer simulation results and theory analysis shows that the proposed structure can achieve the performance close to the traditional receiver which need much higher sample rate at very lower sample rate and avoid interference effectively.
