Confidence bounds for magnitude-squared coherence estimates
E. Scannell, G. Carter · IEEE Transactions on Acoustics Speech and Signal Processing · 1978
In many applications, two received signals are digitally processed to estimate coherence. Results of computing coherence estimate confidence bounds for stationary Gaussian signals are presented. New computationally difficult examples are given for 80 and 95 percent confidence with independent averages of 8, 16, 32, 64, and 128.
