K-best Sphere Decoder Algorithm for Spatial Multiplexing Mimo Systems
To achieve high data rates, reliable data rate transmission and near capacity performance of next generation wireless communication systems iterative processing has been widely considered. However, such an efficient receiver design has been made significant challenge. In this paper, MIMO detection techniques have been investigated which achieves reliable data transmission with less computation ...
متن کاملLow-complexity dominance-based Sphere Decoder for MIMO Systems
The sphere decoder (SD) is an attractive low-complexity alternative to maximum likelihood (ML) detection in a variety of communication systems. It is also employed in multiple-input multiple-output (MIMO) systems where the computational complexity of the optimum detector grows exponentially with the number of transmit antennas. We propose an enhanced version of the SD based on an additional cos...
متن کاملSphere Decoding for Spatial Modulation Systems with Arbitrary Nt
Recently, three Sphere Decoding (SD) algorithms were proposed for Spatial Modulation (SM) scheme which focus on reducing the transmit-, receive-, and both transmit and receive-search spaces at the receiver and were termed as Receiver-centric SD (Rx-SD), Transmitter-centric SD (Tx-SD), and Combined SD (C-SD) detectors, respectively. The Tx-SD detector was proposed for systems with Nt ≤ Nr , wher...
متن کاملA Generalized Sphere Decoder for Asymmetrical Space Time Communication Architecture
Introduction In this letter we focus on the detection prob lem of an asymmetrical multi antenna system We consider a generalization of the well known sphere decoder SD which is used to decode a cellular communication system with N antennas at the mobile and M N antennas at the base station Notation Z is the ring of integers R is the eld of real numbers The matrixM has entries mij M T is the tra...
متن کاملA Fast Generalized Sphere Decoder for Optimum Decoding of Under-determined MIMO systems
A new Generalized Sphere Decoder (GSD) is proposed for optimum decoding of lattice points in a system with fewer equations than unknowns. The proposed algorithm is significantly faster than the one proposed in [1] and is a natural extension of the sphere decoding philosophy introduced in [2, 3]. The complexity reduction is achieved by partitioning the entire range of maximum likelihood hypothes...
