Improved multilevel quantization for detection of narrowband signals

Nearly optimum quantization levels for multileveled quantizers in radar receivers and distributed-detection are calculated for preassigned false-alarm probability Q/sub 0/ by maximizing the detection probability Q/sub d/ after replacing both Q/sub 0/ and (1-Q/sub d/) by the saddlepoint approximations. Narrowband signals of random phase and with both fixed and Rayleigh-fading amplitudes in Gaussian noise are treated, and the loss in signal detectability incurred by quantization is estimated.<
