Two sequential nonparametric detection procedures

In this paper, two sequential detection techniques are described. Most of the expressions are derived under the assumption that one of two antipodal equally probable signals corrupted by an additive, zero-mean symmetrically distributed noise is present at the input to the detector. Without too much difficulty the results can be generalized to include non-antipodal signals and asymmetric noise distributions. The proposed detection procedures preserve the desirable robust properties of nonparametric detection procedures while retaining the basic advantages of sequential procedures
