Overlapped Alamouti Codes
—In most of the existing space–time code designs, achieving full diversity is based on maximum-likelihood (ML) decoding at the receiver that is usually computationally expensiv...

IQ Space Frequency Time Codes for MIMO-OFDM Systems
Abstract: In this paper, we study concatenated coding for MIMOOFDM systems. The proposed concatenated system achieves full spatial and frequency diversity at much lower complexity ...

Partially-coherent distributed space-time codes with differential encoder and decoder
Abstract— Distributed space-time coding is a means of achieving diversity through cooperative communication in a wireless relay network. In this paper, we consider a transmission...

Adaptive Modulation and Coding for Bit Interleaved Coded Multiple Beamforming
— Bit interleaved coded multiple beamforming (BICMB) was previously designed to achieve full spatial multiplexing of min(N, M) and full spatial diversity of NM for N transmit and...
