Improved Robust Multiuser Detection in Flat Fading Asynchronous non-Gaussian Channels

Robust Decorrelating Detector in Multi-Path Fading Under Impulsive Noise

“…A chip-based non-linear front-end for impulsive noise filtering followed by the classical decorrelating decision feedback (DDF) detection has been designed in [8] and it is shown that substantial improvement can be achieved. In [9], an improved robust blind multiuser detection technique based on subspace approach is presented. This approach requires only the signature waveform and the timing of the desired user in order to demodulate user's signal and significantly outperform blind linear decorrelating detector and robust blind multiuser detector (Huber and Hampel M-estimators) in flat fading CDMA channels with impulsive ambient noise.…”

“…Fuzzy decorrelating detector for non-Gaussian CDMA channels is proposed and analyzed in [13]. However, in [5][6][7][8][9][10][11][12][13], the performances of the detectors are not analyzed under multi-path fading.…”
