Quasi-orthogonal space-time-frequency codes in MB-OFDM UWB
Abstract-- The paper examines the implementation of QuasiOrthogonal Space-Time-Frequency Codes (QOSTFCs) to increase data rates and error performance in recently proposed STFC Multiband OFDM Ultra Wideband (MB-OFDM UWB) communications systems. It is shown that, an order-4 QOSTFC not only can provide the full rate, but also may provide significantly better error performance, compared to the conventional MB-OFDM (without STFCs), and considerably better error performance, compared to order-4, orthogonal STFC MBOFDM, without increasing the total transmission power.
