Quadrature amplitude modulation (QAM), with its uniform distribution, exhibits an asymptotic
sha**-loss of πe/6 (≈ 1.53 dB) with increasing signal-to-noise-ratio compared to the …

This monograph summarizes the special functions needed in the performance analysis of
wireless communications systems. On the basis of special Gaussian and Owen functions …

Motivated by a recent surge of interest in convex optimization techniques,
convexity/concavity properties of error rates of the maximum likelihood detector operating in …

This paper provides a new, exact, and general expression involving 1-D and 2-D Q-
functions for the bit error probability of M-ary phase-shift keying (MPSK) under additive white …

A signal space diversity (SSD) scheme is one of techniques to achieve diversity gain in
fading channels. This method consists of two key operations: constellation rotation and …

Network coding notions promise significant gains in wireless networks' throughput and
quality of service. Future systems employing such paradigms are known to be also highly …

In this thesis bit-interleaved coded multicarrier transmission at high spectral efficiency is
studied from a bit-level perspective. The analysis is based on an equivalent representation …

High-order modulations are necessary to improve the bandwidth efficiency of the satellite
communication system. However, the non-linear characteristic of satellite channels limits the …

In the popular bit-interleaved coded modulation (BICM) the output of the channel encoder
and the input of the modulator are separated by a bit-level interleaver. From the decoder's …
