CFAR TMDA burst detection schemes for constant modulus signals

In this paper, the performances of burst detection schemes which employ constant false-alarm rate (CFAR) algorithms are analyzed and compared. These schemes can be used for a typical time division multiple access (TDMA) protocol. The burst detection probabilities and corresponding false-alarm probabilities are derived to understand the effect of the received signal quality degradation at the receiver for any constant modulus signals. The burst detection probabilities are expressed as a function of the received signal quality measure which can be expressed as a function of cross-ambiguity function. Two particular detection schemes, namely, the single window ratio detection (SWRD) scheme and the double window ratio detection (DWRD) scheme, are compared in terms of the robustness against the degradation of the received signal quality
