Detailed step-by-step numerical procedures for computing the normalized detection threshold for the FFT J-out-of-L detector are presented. Accurate approximations are also provided for cases where numerical procedures break down due to rounding errors. Some of the numerical procedures detailed here are also useful in other signal processing problems.
