Optimized precoded spatio-temporal partial-response signaling over frequency-selective MIMO channels

Due to the continuous demand for higher bit rates, the management of the spatio-temporal intersymbol interference in frequency-selective multiple-input multiple-output (MIMO) channels becomes increasingly important. For single-input single-output …

Computationally-efficient iterative demodulation of coded PSK signals affected by phase noise

This paper considers two recently-proposed receivers, Tikh and DCT. Both receivers are computationally-efficient, iterative and designed to be robust against phase noise on the local oscillators of digital bandpass communication systems. The …

Block-processing soft-input soft-output demodulator for coded PSK using DCT-based phase noise estimation

This paper considers the detection of coded phaseshift keying signals subjected to additive white Gaussian noise and oscillator phase noise. We propose a detector that partitions the received frame into smaller blocks and models the unknown phasor …

Analysis and efficient evaluation of the BER of OSTBCs with imperfect channel estimation in arbitrarily correlated fading channels

An analysis of the exact bit error rate (BER) performance of orthogonal space-time block codes (OSTBCs) with maximum-likelihood detection in the presence of channel estimation errors is presented. The possibly correlated coefficients of the …

Channel characterization and robust tracking for diversity reception over time-variant off-body wireless communication channels

In the 2.45 GHz band, indoor wireless off-body data communication by a moving person can be problematic due to time-variant signal fading and the consequent variation in channel parameters. Off-body communication specifically suffers from the …

USING SINGULARITY ANALYSIS TO APPROXIMATE TRANSIENT CHARACTERISTICS IN QUEUEING SYSTEMS

In this article, we develop a simple method to approximate the transient behavior of queueing systems. In particular, it is shown how singularity analysis of a known generating function of a transient sequence of some performance measure leads to an …

A generic approximate transient analysis applied to a priority queue

In this paper, we develop an efficient method to approximate the transient behavior of queueing systems. More precisely, it is shown how singularity analysis of a known transform function of a transient sequence leads to an approximation of this …
