Abstract [en]

In this paper, we propose a novel STF (Space-Time-Frequency) code for use in MB-OFDM UWB (Multiband-Orthogonal Frequency Divvision Multiplexing based Ultra-WideBand) systems with multiple antennas. These codes guarantee a rate of one symbol per channel use and result in moderate decoding complexity. Further, in conjunction with hopping multiband OFDM modulation, these codes are shown to exploit the spatial and frequency divversities available in MIMO UWB systems for channels with arbitrary PDPs (Power Delay Profiles). A systematic procedure to enhance the coding gain of these codes in the absence of PDP information at transmitter is also presented. BER (Bit Error Rate) performance of these codes is shown to be better than those of existing codes due to the systematic coding gain enhancement.
