Type: White Paper
Rating: (0)

Overview: While rapid variations of the fading channel cause InterCarrier Interference (ICI) in Orthogonal Frequency-Division Multiplexing (OFDM), thereby degrading its performance considerably, they also introduce temporal diversity, which can be exploited to improve the performance. This research paper from Institute of Electrical and Electronics Engineers derives a Matched-Filter Bound (MFB) for OFDM transmissions over doubly selective Rayleigh fading channels, which benchmarks the best possible performance if ICI is completely canceled without noise enhancement.
