A ddvice for determining the rate of a received communication frame includes a plurality of encoded signal quality estimators (606, 608, 610), each at a different rate, a decision controller (622), connected to the signal quality estimators (606, 608, 610), a decoder (626) connected to the controller (622) and an erasure detection unit (624) connected to the decoder (626) and the controller (622). Each of the quality estimators (606, 608, 610) processes the received encoded frame according to an encoded signal quality criteria, thereby producing a quality value. The controller (622) selects the rate with the best quality value, the decoder (626) decodes the encoded frame according to the selected rate and the erasure detection unit (624) analyzing the decoded frame, thereby determining it as allowed or as erased.
