Minimum Bit Error Rate Multiuser Detection in Multiple Antenna Aided OFDM

, 2003
In this contribution, we propose a Minimum Bit Error Rate (MBER) multiuser detector for Space Division Multiple Access (SDMA) aided Orthogonal Frequency Division Multiplexing (OFDM) systems. It is shown that the MBER detector outperforms the Minimum Mean

Generalised MBER-based vector precoding design for multiuser transmission

, 2011
We propose a generalized vector precoding (VP) design based on the minimum bit error rate (MBER) criterion for multiuser transmission in the downlink of a multiuser system, where the base station (BS) equipped with multiple transmitting antennas ...

On multi-user EXIT chart analysis aided turbo-detected MBER beamformer designs

, 2008
This paper studies the mutual information transfer characteristics of a novel iterative soft interference cancellation (SIC) aided beamforming receiver communicating over both additive white Gaussian noise (AWGN) and multipath slow fading channels. Based

Establishing a Spectral Optical CDMA System Involving the Use of Two Mutually Orthogonal States of Polarizations Using 1-D Two-Distinct Codes With Two-Code Keying

IEEE Access
We propose 1-D Two-Distinct codes with two-code keying (TCK) using two mutually orthogonal states of polarization (SOP) in spectral components as a new code family for spectral amplitude coding (SAC) in optical code division multiple access (OCDMA ...

Interference reduction in multiuser relay networks

, 2014
In future multiuser wireless systems, the limited system resources have to be extensively reused for serving several users. This results in received interferences at the users which limit the performance of the system. A scenario with several source-destination node pairs communicating unidirectionally through a shared medium is considered.
