Optimum noncoherent FM-DCSK detector:: Application of chaotic GML decision rule

A new detector configuration is proposed for the detection of FM-DCSK signals with improved noise performance. Since the new detector configuration is developed directly from the chaotic GML decision rule, it offers the best noise performance in AWGN channel in the category of noncoherent detection if the reception of a single isolated symbol and memoryless modulation scheme is considered. The paper shows how the a priori information on chaotic signals may be exploited in waveform communication to maximize the noise performance.
