Performance Evaluation of Linear Detectors for LDPC-Coded MIMO Systems

This paper investigates the performance of linear detectors namely the Minimum Mean-Squared-Error (MMSE) and the Zero-Forcing (ZF) suboptimal detection schemes for Multiple Input Multiple Output (MIMO) signals over an additive white Gaussian noise (AWGN) channel. Unlike the ZF detector which suffers from noise enhancement, it will be shown that the MMSE detector which takes noise into account p...

LDPC Coded Turbo Equalization for MIMO System

—In this paper, MIMO (Multiple-Input-Multiple Output) system based on turbo equalization techniques which LDPC (Low Density Parity Check) codes were outer code and STTC (Space Time Trellis Code) were employed as an inner code are studied. LDPC decoder and STTC decoder are connected through the interleaving and de-interleaving that updates each other's information repeatedly. On the receiver si...

LDPC Coded MIMO Communication System With Relay Selection

This paper presents a low-density parity check(LDPC) coded multiple-input multipleoutput(MIMO) cooperative communication system with relay selection strategy. In the proposed cooperative network with multiple potential relays, we present selection cooperation to choose the best relay. We also present the outage probability analysis of this system. Furthermore, in the proposed architecture relay...

Low-Complexity LDPC-Coded USTM Noncohereny MIMO Receivers

This paper proposes a scheme of combining low-density parity check (LDPC) code with unitary space time modulation (USTM) for noncoherent multiple-input-multiple-output (MIMO) transmitter and receiver over Rayleigh block fading and additive white Gaussian noise (AWGN) channel. The main aim is to design the low complexity coded noncoherent MIMO receiver which is completely dependent on the struct...
