Space-Time-Frequency Coded for Multiband-OFDM Based on IEEE 802.15.3a WPAN

In this paper, Multiband-OFDM UWB system based on IEEE 802.15.3a standard is studied and simulated with spatial, time and frequency (STF)coding scheme. The using of STF coding method can guarantee both full symbol rate and full diversity advantages. The simulation results show that the STF code uses multi-path-rich and random-clustering characteristics of UWB channel environment on the performance of MB-OFDM system.
