Abstract:

An experimental investigation of perception of narrowband, Gaussian signals was performed. A new technique, using a reference sine wave, a stiff limiter, and a harmonic-zone filter, was in investigated. The technique used both energy and gross phase characteristics of the Gaussian signal in the perception process. The comparison of this new technique with energy detection showed equal signal perception at 3-db lower SN ratios for perception probabilities greater than 0.5 at fixed, false-alarm probabilities of 11000, 110,000, 1100,000, and 10 to the minus 6th power.
