2. 1. Maximum likelihood detection for the linear MIMO channel

   Author : Joakim Jaldén; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

   Abstract : this thesis the problem of maximum likelihood (ML) detection for the linear multiple-input multiple-output (MIMO) channel is considered. The thesis investigates two algorithms previously proposed in the literature for implementing the ML detector, namely semide nite relaxation and sphere decoding. READ MORE

   Abstract : Three-node relay channels which consist of a source, a relay and a destinationare considered in this thesis. In the first part, an uncoded relay channelis studied. READ MORE

6. 4. Efficient Coding Techniques for Networks & Channels with Transmission Errors

   Author : Ming Xiao; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channels with Errors; Low-Density Generation-Matrix Codes; Sink Bit Error Probability; Continuous Phase Modulation; Maximum-Likelihood Decoding; Cross-Layer Design; Network Coding; Ring Convolutional Codes; Adaptive Codes.; Deterministic Rateless Codes;

   Abstract : This thesis consists of two parts, both of whichinvestigate coding techniques for information transmission throughchannels in the presence of errors. Part I discusses topics ofnetwork coding and rateless codes. Part~II considers channel codesfor continuous phase modulation. These two parts are clearlydifferent, but they are also related.

7. 5. On Bit-Wise Decoders for Coded Modulation

   Author : Mikhail Ivanov; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit-error probability; L-values; labeling; Gray code; coded modulation; log-likelihood ratio; maximum likelihood decoder; Additive white Gaussian noise; quadrature amplitude modulation.; interleaver; flat fading channel; pairwise error probability;

   Abstract : Coded modulation is a technique that emerged as a response to the growing demand for high data rates. It was devised to achieve high spectral efficiency with high reliability, potentially approaching Shannon’s capacity. The main idea of coded modulation consists in combining error-correcting coding with higher-order modulation. READ MORE
