Techniques for performing low-latency blind rate detection of a frame, wherein the frame is divided into a plurality of sub-segments. In an exemplary embodiment, symbols of a primary sub-segment of a frame are received and deinterleaved to recover information bits and at least one quality metric for each of a plurality of rate hypotheses. Symbols of a secondary sub-segment of the frame are also received and deinterleaved to recover information bits and at least one quality metric for each of the plurality of rate hypotheses. The recovered information bits and quality metrics for each rate hypothesis may be compared between the primary and secondary sub-segments to select the most likely rate hypothesis. In an exemplary embodiment, the at least one quality metric may include a frame quality indicator (FQI) such as a cyclical redundancy check (CRC).
