Abstract
There is provided a mechanism for error detection comprising: detecting the symmetry of error distributions over adjacent time intervals and muting of a radiotelephone in response to detected loss of substantial symmetry, unless errors are attributable to valid alternative detections. It is further characterized by: detecting the symmetry of error distributions over adjacent time intervals and muting a radiotelephone as a corrective response to detected consequential asymmetry or loss of substantial symmetry (unless errors are attributable to alternative detections of valid synchronization words) and cancelling any such corrective response upon subsequent alternative detections of valid synchronization words.
