In a multiple-input multiple-output (MIMO) multi-band orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) system, coherent detection where the channel state information (CSI) is assumed to be exactly known at the receiver requires the transmission of a large number of symbols for channel estimation, thus reducing the bandwidth efficiency. This paper examines the use of unitary...
Cooperative communication has been intensively considered for general wireless and sensor networks. However, it has been almost untouched in space-time-frequency coded multi-band OFDM ultra-wideband (STFC MB-OFDM UWB) systems. This paper thus proposes two cross-layer designs for cooperative communication, namely simple cooperative communication scheme (SCCS) and advanced cooperative communication...
