Iterative Receiver Techniques for Coded Multiple Access Communication Systems

A Thesis for the Degree of Master Iterative Receiver Design for Coded MIMO Systems on SC/OFDM Transmission

Recently, researches on multiple-input multiple-output (MIMO) technique deploying multiple transmit and receive antennas have abruptly emerged due to its potential to greatly improve spectral efficiency. Representatively, V-BLAST (Vertical Bell Laboratories Layered Space-Time) architecture has been widely accepted for the fourth generation mobile communications, such as IEEE 802.16e and 3GPP-LT...

EM-based iterative receiver for coded MIMO systems in unknown spatially correlated noise

We present iterative channel estimation and decoding schemes for multi-input multi-output (MIMO) Rayleigh block fading channels in spatially correlated noise. An expectation-maximization (EM) algorithm is utilized to find the maximum likelihood (ML) estimates of the channel and spatial noise covariance matrices, and to compute soft information of coded symbols which is sent to an error-control ...

An iterative receiver for coded OFDM systems over time-varying wireless channels

This paper presents a low-complexity iterative receiver for coded OFDM systems. We present an EM-based iterative algorithm for combined channel estimation and decoding that makes collective use of the available data and system constraints. Minimum number of pilots are sent only in the first symbol of the packet to acquire the channel; then the iterative algorithm is used to track the channel ti...

Robust iterative multiuser receiver for coded CDMA systems in non-Gaussian channels

A robust front-end pre-filter incorporating non-quadratic signal processing techniques is proposed. We will demonstrate the effectiveness of this filter in suppressing impulsive noises in a coded direct sequence code-division multiple access (DS-CDMA) communication system. Based on M-Estimation approach, the pre-filter works by minimizing an appropriate penalty function in an iterative fashion ...
