ABSTRACT:
A method of determining a rate associated with a received signal including the steps of detecting the received signal (40); decoding the received signal at a first rate, determining a first path metric associated with the first rate, decoding the received signal at a second rate, and determining a second path metric associated with the second rate (44); calculating a plurality of discriminant functions based on the first and second path metrics (46); comparing at least one of the plurality of discriminant functions to a first predetermined value (48); and selecting one of the first and second rates as a determined rate based on the comparison.
