Analysis of FDSS ultra-wideband six-port receiver

The ultra wideband (UWB) radio system is an emerging wireless radio technology. It can transmit digital data over a wide spectrum of frequency band with very low power. This paper presents an analysis of UWB technology on a direct millimeter wave six-port receiver, to be designed as an application-specific integrated receiver using the frequency diversity spread spectrum (FDSS) technique. With wideband six-port circuits and other analog circuits, the proposed receiver provides a simple means to obtain a multi-chip module (MCM) for QPSK communications. Simulation results of BER and noise performance of the UWB six-port based receiver are shown and discussed.
