Abstract
Techniques for more accurately detecting the data rate of a frame of data in a cellular telephone system are described. Data is preferably received at one of four rates: full, half, quarter and eighth. A correlation is performed between the incoming soft data and the data generated by re-encoding and re-repeating the data. Variations on the approach make it readily possible to accurately perform rateset 1 or rateset 2 rate detection.
