Abstract—In this paper, we develop and analyze the basic methodology for minimum-energy (ME) band-limited prediction of sampled time-variant flat-fading channels. This predictor is based on a...
MAP Channel-Estimation-Based PIC Receiver for Downlink MC-CDMA Systems (2008)
We propose a joint MAP channel estimation and data detection technique based on the expectation maximization (EM) method with paralel interference cancelation (PIC) for downlink multicarrier (MC)...

Precoding for Downlink Block-Transmission in DS-CDMA Systems with Multipath Channels (2007)
Joachim Dahl Jakob, Jakob Stoustrup, Bernard H. Fleury, Søren Holdt Jensen
We investigate precoding of the information symbols before spreading for downlink DS-CDMA systems subject to multipath fading. With precoding, a conventional receiver (RAKE) can achieve performance...

Time-Variant Channel Prediction Using Time-Concentrated and Band-Limited Sequences (2006)
Thomas Zemen, Christoph F. Mecklenbräuker, Bernard H. Fleury, Forschungszentrum Telekommunikation Wien
We present the basic methodology for minimumenergy bandlimited prediction of time-variant flat Rayleighfading channels. This predictor is based on a subspace spanned by time-concentrated and...
Time-Variant Channel Prediction Using (2006)
Time-Concentrated And Bandlimited, Thomas Zemen, Christoph F. Mecklenbräuker, Bernard H. Fleury, Corresponding T. Zemen, Forschungszentrum Telekommunikation Wien
We use time-concentrated and bandlimited sequences for minimum-energy prediction of timevariant flat-fading channels. The time-concentration of these sequences is matched to the length of the...
