Can I read LDPC-Coded 8PSK Design Techniques on EtoBox?

LDPC-Coded 8PSK Design Techniques by Nitesh Chilakala is a document available to read on EtoBox.

What is LDPC-Coded 8PSK Design Techniques about?

This document describes a system for designing LDPC-coded modulation schemes using 8PSK signaling. It presents a block diagram of the system including an LDPC encoder, 8PSK modulator, AWGN channel, and MAP symbol-to-bit metric calculator at the receiver. It analyzes the receiver and shows that the outputs of the symbol-to-bit metric calculator have approximately Gaussian distributions, allowing the use of a Gaussian approximation algorithm for code design instead of brute force methods.
