We consider the problem of digital communication in a fading environment using the Multi-Carrier CDMA technology. By incorporating the effect of the pulseshaping filter in the channel estimation and signal detection modules, we develop new estimator and detector structures which significantly outperform the commonly used timedomain equalizers and matched(More)
We consider the problem of digital communication in a Rayleigh flat fading environment using a multiple antenna system. We assume that the transmitter doesn’t know the channel coefficients, and that the receiver has only an estimate of them. We further assume that the transmitter and receiver know the statistics of the estimation error. We will refer to(More)
The supply of high data rates is a major goal of the communication industry. Towards this goal one solution is to use high level modulation combined with powerful coding. We propose a turbo-coded high-level modulation system (16/32/64-QAM) for the downlink that could be used for example in the future evolution of the EGPRS. The evaluation of such a system(More)
