We propose two methods for deterministic blind equalization of linear time- varying (LTV) channels with multiple users. Our approach is based on an LTI (linear time invariant) multichannel representation of LTV channels. With the first method, the multiuser channel is equalized up to an instantaneous mixture that is subsequently resolved by means of a POCS (projections onto convex sets) algorithm. ...

Orthogonal frequency division multiplexing (OFDM) is sensitive to carrier frequency offset and channel estimation error, which destroy the subcarrier orthogonality and give rise to intercarrier interference (ICI). This paper addresses the performance degradation due to imperfect parameters in an orthogonal frequency and code division multiplexing (OFDM-CDM) system with multiple transmit antennas. For the performance evaluation, the average bit error rate ...

An OFDM system with the decision-aided channel tracking technique for a long frame application is proposed. The OFDM system in wireless LAN applications assumes static channel response in a short frame and it is enough to use two long training symbols for channel estimation. We build a wireless surveillance system which may transmit data symbols in a seamless manner. The ...

This paper studies the problem of minimizing the queueing delay for a time- varying channel with a single queue, subject to constraints on the average and peak power. First, by separating the time-scales of the arrival process, the channel process and the queueing dynamics it derives a heavy-traffic limit for the queue length in the form of a reflected diffusion ...

This paper proposes a joint carrier recovery and blind decision feedback equalizer (DFE) based on stop-and-go MCMA and decision-direct least-mean- square (SG-MCMA-DD-LMS) algorithm. The equalizer initially operates in modified constant modulus algorithm (MCMA) mode under stop-and-go principle to compensate the channel distortion and acquire phase offset. When the channel eye is opened equalizer switches to decision-direct least-mean-square (DD-LMS) mode to ...
