Abstract
The effect of normalization and quantization on the detection performance of a long-term spectal integrator is examined. The performance is described by the receiver operating characteristic, which is computed numerically from the probability density function of the detecion statistic. It is found that the loss in performance due to normalization is small, less than 0.2 dB for an example case. The loss due to quantization depends on the number of bits used. When the quantizer uses only one bit (two levels), the loss is approximately 1dB. This loss can be decreased to less than 0.1 dB by the use of three bits (8 levels) in the quantizer.
