Near optimum low complexity MMSE multi-user detector
نویسندگان
چکیده
In this paper we propose a novel multiuser detector for the synchronous CDMA system. Its BER performance approaches to the optimum MMSE multiuser detector while the complexity only polynomially increases to the number of active users. We also demonstrate its complexity and performance over optimnm MMSE multiuser detector and decorrelator. In addition to synchronous AWGN channel case, we also provide the mechanism for the case of asynchronous case, Rayleigh fading channel case, and frequency selective channel case.

Near-ML multiuser detection with linear filters and reliability-based processing
The prohibitive—exponential in the number of users—computational complexity of the maximum-likelihood multiuser detector for direct-sequence code-division multiple-access communications has fueled an extensive research effort for the development of low-complexity multiuser detection alternatives. In this letter, we show that we can efficiently and effectively approach the error rate performance...
متن کاملOptimum and sub-optimum linear MMSE multi-user detection for multi-carrier CDMA transmission systems
This paper investigates optimum and sub-optimum linear Minimum Mean Square Error (MMSE) Multi-User Detection (MUD) techniques for multi-carrier code division multiple access transmission systems. In a first step, we present two formulations of MMSE MUD techniques that are optimum for any number of users and any power distribution and achieve exactly the same performance with a different computa...
متن کاملHybrid local search polynomial-expanded linear multiuser detector for DS/CDMA systems
This work proposed a new multiuser detector for DS/CDMA systems constituted by the polynomial MMSE detector followed by a local search algorithm 1-adapt LS (one-adaptive local search), namely the Hybrid 1adapt-LS-MuD. In order to reduce computational complexity inherent to recurrent computation of the cross-correlation matrix inverse in DS/CDMA multiuser detection (MuD), this work introduces fo...
متن کاملLinear Differentially Coherent Multiuser Detection for Multipath Channels
By combining multipath processing, differential signal detection, and multiuser detection techniques, we develop a class of near-far resistant linear detectors for differentially coherent multipath signals. We derive and establish performance relationships among the following detectors: an optimally near-far resistant detector, a suboptimum detector which does not require knowledge of the signa...
متن کاملImproved Multistage Detector by Mean-Field Annealing in Multi-User CDMA
We propose a multistage multi-user detector for Code Division Multiple Access that implements Mean-Field Annealing. Annealing is a well known technique to avoid local minima in detection and optimisation problems. Local minima certainly occurs in CDMA multi-user detection leading to anomalous Bit Error Rate curves. Annealing is implemented as a standard multi-user detector implementing interfer...
