In this paper, we introduce a novel Markov chain (MC) representation aided minimum bit error rate (MBER) detection method that is applicable to an M-QAM modulated SDM/SDMA uplink system. Compared to the conventional MBER scheme, the proposed MC-MBER scheme is capable of reducing the complexity imposed with the aid of its efficient detection candidate set generation assisted by the Markov chain process...
In this contribution we propose a space-time decision feedback equalization (ST-DFE) assisted multiuser detection (MUD) scheme for multiple antenna aided space division multiple access systems. A minimum bit error rate (MBER) design is invoked for the MUD, which is shown to be capable of improving the achievable bit error rate performance over that of the minimum mean square error (MMSE) design. An...
A novel iterative multiuser detector (MUD) is proposed for employment in space division multiple access (SDMA) aided orthogonal frequency division multiplexing (OFDM) systems, where the uplink transmissions of the users share the same bandwidth. The individual users' signals are differentiated with the aid of their unique user-specific channel impulse responses (CIRs). The MUD commences its operation...
