System for detecting defective speech frames in a receiver by calculating the transmission quality of an included signal within a GSM communication system

摘要: A method for detecting defective speech frames in a receiver of communication system includes coded signal consisting conveying coding parameters received through transmission link. The detection depends on the quality If link is "poor", unusual parameter values frame are interpreted as errors, and classified defective. During "good" quality, all possible accepted forwarded to decoder. In latter mode operation, solely based conventional error methods employed receiver.
