Design and Performance of Multi-Band OFDM UWB System with Multiple Antennas

In this paper, we design Multi-Band OFDM (MB-OFDM) UWB systems, with two transmit and two receive antennas, with the goal of achieving 1 Gbps data rate. We study the performance of these systems with different modulation schemes. The Packet Error Rate (PERs) and the operating range of these systems are obtained using frequency domain baseband simulations as well as more realistic full-system simulations, and are compared to those of single antenna systems. Simulation results show that the MHVIO MB-OFDM systems provide significant gains for 1 Gbps transmission over single antenna MB- OFDM UWB systems.
