Analysis of channel interference on the parallel-structured MIMO-UWB transceiver

Sunam Kim; Sunwoong Choi; Ki-Doo Kim

The purpose of this paper is to analyze the channel interference of MIMO-UWB transceiver and to observe its effect on the system performance. We propose a new MIMO-UWB transceiver where the parallelized structure is employed in order to reduce the high clock speed of UWB applications and both ML and LS techniques are used to resolve the ISI caused by multi-path. Through the simulation, the channel characteristics are investigated and the effect of interferences caused by correlation is analyzed over WPAN environment.
