Abstract :
We propose a novel receiver for coded orthogonal/biorthogonal frequency division multiplexing (OFDM/BFDM) communications over time-varying mobile radio channels. The receiver uses decision-directed predictive equalization and thus does not require regular transmission of pilot symbols. An optimum channel predictor and its efficient implementation are discussed, and simulation results are presented
