Abstract
A method of monitoring the performance of a Viterbi detector by using the deviations from the noiseless case of the path difference of the two branches entering the minimal state for a number of samples.
Claims7
A method of assessing the bit error rate with a sequential detector, comprising the steps of:
- (a) estimate the margin between two path metrics entering a state for each state along the maximum likelihood path through a trellis;
- (b) use the estimate of step (a) to assess the bit error rate.
A method of channel quality control, comprising the steps of:
- (a) estimate the margin between two path metrics entering a state for each state along the maximum likelihood path through a trellis;
- (b) use the estimate of step (a) to assess the bit error rate;
- and
- (c) adapt a channel in response to the assessment of step (b).
