Abstract:
1. A mobile station providing communication in a digital communication system, comprising: a receive part; a corrector that determines symbol values from data received by said receive part and that provides decision values representative of associated symbol values being correctly determined; a threshold selector; a comparator that receives said decision values and a threshold value from said threshold selector and that generates a detection when a decision value is less than said threshold value, said detection indicative of a low confidence level in the correctness of a determined symbol value associated with said decision values; and an accumulator that receives detections from said comparator, said accumulator configured as a counter to maintain a count of said detections, indicative of decision values that are less than said threshold value during a sequence of data received by said receive part, and to increment said maintained count of said detections each time said comparator indicates said decision value is less than said threshold value and to provide said maintained count of said detections for formation of a bit error rate estimation of said sequence of data from an adjustable total number that is proportional to a number of data bits in data received by said receive part.
