The paper examines the potential of the implementation of high-order Space-Time-Frequency Codes (STFCs) in recently proposed STFC Multi-Band OFDM Ultra Wideband (MB-OFDM UWB) communications systems, and compares the performance of two different code structures of order-8 to that of the Alamouti code and of the conventional MB-OFDM UWB system (without STFCs). It is shown that an order-8 STFC provides significantly better error performance, compared to the Alamouti STFC, and much better error performance, compared to the conventional MB-OFDM, without increasing the total transmission power. It is also shown that, for the same total transmission power, the order-8, fully structured code that we proposed previously for conventional wireless Multiple-Input Multiple-Output (MIMO) Space-Time Block Codes (STBCs) communications is an advanced code, providing the best error performance.
