Noncoherent double-filter detection of FSK and DPSK signals with diversity
Desmond P. Taylor, Giorgio Matteo Vitetta · 2003
Linearly time-varying fading models are used to investigate both noncoherent detection of FSK signals and differential detection of PSK signals over frequency-flat fading channels. The structure of the optimal FSK and DPSK detectors is derived and an analytical technique is proposed to compute their error performance in fast fading.
