Summary form only given, as follows. A nonparametric sequential testing procedure for the detection of constant signal in additive symmetric noise is proposed and analyzed. The nonparametric test is obtained by first quantizing all the observations into their signs and then applying the Lee-Thomas modifed sequential procedure to the quantized observations or their sufficient statistic. The procedure is extended to a distributed system consisting of two local detectors and a global decision maker. A simple truncation scheme is considered and is shown to maintain the nonparametric property while efficiently limiting the random test duration. Numerical results are presented to illustrate the performance gain and to demonstrate the simplicity of the test structure.
