A multi-rate data receiver includes a decoding section for processing the received encoded data symbols via multiple paths to make a determination as to the rate of the received data. A statistical analysis is made of the incoming data prior to decoding, and rate selection made among one of the multiple highest rates. If the determination is not that the data is associated with the highest rate, the data is processed through multiple parallel decoding paths and the decoded data on the output thereof evaluated to determine which of the multiple paths is acceptable and associated with the incoming data rate.

1. In a receiver of a variable-rate communication system, a method for determining a data rate of a received signal having contained therein encoded data, comprising the steps:receiving the encoded data; evaluating the encoded data utilizing predetermined data rate criteria to determine if the encoded data is associated with at least one data rate; if the data rate is determined in the step of evaluating to be at the at least one data rate, then decoding the encoded data at the at least one data rate; if the data rate is determined in the step of evaluating to not be at the at least one data rate, then: decoding the encoded data at multiple different data rates other than the at least one data rate in separate decoding operations for each rate; evaluating the quality of the decoding operation at the output of each of the separate decoding operations at the multiple different data rates; comparing the results of the evaluation step of the quality of the multiple and separate decoding operations to predetermined selection criteria; and selecting the one of the multiple separate decoding operations that meets the predetermined selection criteria and outputting the decoded data therefrom as the desired decoded data.
