Exact Detection Performance of Multiple-Pulse Frequency-Shift Signals in a Partially-Correlated Fading Medium with Generalized Noncentral Chi-Squared Statistics
Abstract
The transmitted signal consists of K pulses separated in time, frequency space so as to be nonoverlapping. In passing through the medium to the receiver, each signal pulse is subjected to fading. In particular, pulse pairs which are closely spaced in time, frequency space can fade in a highly dependent fashion, while those more widely separated can have relatively independent fading behavior; that is, the transmitted frequency-shift-keyed signal pulses undergo partially-correlated fading of a very general character that contains both deterministic components as well as random components. The amplitude-fading statistics are not limited to be Rayleigh. Additive zero-mean Gaussian noise, which is stationary over the total signal transmission time and which has a flat spectrum over the total signal bandwidth, is present at the input to the receiver, in addition to the fluctuating signal pulses (when present).
