Randomization and Dithering in Quantized Signal Detection Systems

摘要

Several versions of data quantizers are considered as detection nonlinearities in a binary signal detection problem. Randomized and dithered versions of these quantizers are formulated and the performance of all proposed systems is compared to that of systems using some well-known detection nonlinearities. In particular, the robustness of the quantizer systems in noise with uncertain statistics is compared to that of the well-known systems via asymptotic relative efficiency. (Author)
