Executive Summary

Is an emerging technology for high speed short range communications. However, the challenge of high speed sampling increases the cost of receiver circuitry such as Analog-to-Digital Converter (ADC). In this paper, the authors propose the utilization of compressive sensing frame work to achieve great reduction of sampling rate. The basic idea is based on the observation that the received signals are sparse in the time domain due to the limited multipath effects at 60 GHz wireless transmission. According to the compressive sensing theory, by carefully designing the sensing scheme, sub-Nyquist rate sampling of the sparse signal still enables exact recovery with overwhelming probability. In the proposed scheme, they offers prototype implementation of low speed A/D conversion for 60 GHz UWB received signal.
