Abstract
A method and device for determining a frame rate of a data fame transmitted over a variable rate communication system. In one embodiment, the present invention receives demodulated soft symbols representing a data frame transmitted at a certain frame rate. The present invention then generates a plurality of decoded bit streams from the demodulated soft symbols, where each of the plurality of decoded bit streams is for testing one of a plurality of rate hypotheses for the frame rate of the data frame. The present invention next re-encodes each of the plurality of decoded bit streams to generate a plurality of re-encoded bit streams, each of which corresponds to a plurality of decoded bit streams.
