Abstract :
The optimum decision level for envelope-detected on/off amplitude-shift keying (ASK) in Gaussian noise is a complex function of the signal/noise ratio. A practical method is described which allows the decision threshold to be automatically extracted from the values at the decision instants of the binary levels.
