Six-Port Architecture based Receiver for MB-OFDM UWB Systems

In this paper, we present the investigation of a six-port architecture based receiver for multi-band OFDM ultra- wide band (UWB) systems. An UWB system simulator is implemented in MATLAB for specification compliant signal processing according to and is represented by transmitter and receiver models. A six-port based receiver is presented which is used in the RF front-end of an UWB system. Its model includes six-port specific errors addressed in following case studies. Additionally, a performance influencing receiver environment is taken into account when we investigate the suitability of six-port architecture for UWB. We conclude this work by system performance evaluation under the considered application scenario.
