Abstract
Abstract Device for determining the rate of a received communication frame, including a plurality of encoded signal quality estimators, each at a different rate, a decision controller, connected to the encoded signal quality estimators, a decoder connected to the controller and an erasure detection unit connected to the decoder and the controller, wherein each of the quality estimators processes the received encoded frame according to an encoded signal quality criteria, thereby producing a quality value, wherein the controller selects the rate with the best quality value, the decoder decodes the encoded frame according to the selected rate and the erasure detection unit analyzing the decoded frame, thereby determining it as allowed or as erased.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
169 words
A receiver to receive a signal frame encoded at a particular one of a set of rates, the receiver comprising: a combined decoder and rate quality estimator to decode said signal frame at a predetermined rate from said set of rates, to produce a quality value for said predetermined rate, and to provide said decoded signal frame to said receiver when said quality value for said predetermined rate exceeds a predetermined threshold; and two or more rate quality estimators coupled to said combined decoder and rate quality estimator, each of said rate quality estimators having associated therewith a different one of said set of rates which is not said predetermined rate, each able to process said signal frame at its associated rate to produce a quality value for said associated rate without decoding said signal frame, wherein said receiver is able to decode said signal frame at the associated rate whose quality value is best when the quality value for said predetermined rate does not exceed said predetermined threshold.
Claim 2
Dependent Claim
169 words
A receiver to receive a signal frame encoded at a particular one of a set of rates, the receiver comprising: a combined decoder and rate quality estimator to decode said signal frame at a predetermined rate from said set of rates, to produce a quality value for said predetermined rate, and to provide said decoded signal frame to said receiver when said quality value for said predetermined rate exceeds a predetermined threshold; and two or more rate quality estimators coupled to said combined decoder and rate quality estimator, each of said rate quality estimators having associated therewith a different one of said set of rates which is not said predetermined rate, each able to process said signal frame at its associated rate to produce a quality value for said associated rate without decoding said signal frame, wherein said receiver is able to decode said signal frame at the associated rate whose quality value is best when the quality value for said predetermined rate does not exceed said predetermined threshold.
Claim 3
Dependent Claim
20 words
The receiver of claim 1 , further comprising: a controller to identify said associated rate whose quality value is best.
Claim 4
Dependent Claim
111 words
A receiver to receive a signal frame encoded at a particular one of a set of rates, the receiver comprising: a host; a first decoder to decode said signal frame at a first rate of said set of rates and to provide said decoded signal frame to said host if correctly decoded at said first rate; and a second decoder to receive said signal frame from said first decoder when said first decoder fails to correctly decode said signal frame, to decode said signal frame at a second rate of said set of rates, and to provide said decoded signal frame to said host if correctly decoded at said second rate.
Claim 5
Dependent Claim
111 words
A receiver to receive a signal frame encoded at a particular one of a set of rates, the receiver comprising: a host; a first decoder to decode said signal frame at a first rate of said set of rates and to provide said decoded signal frame to said host if correctly decoded at said first rate; and a second decoder to receive said signal frame from said first decoder when said first decoder fails to correctly decode said signal frame, to decode said signal frame at a second rate of said set of rates, and to provide said decoded signal frame to said host if correctly decoded at said second rate.
Claim 6
Dependent Claim
120 words
A receiver to receive a signal frame encoded at a particular one of a set of rates, the receiver comprising: two or more rate quality estimators each having associated therewith a different one of said set of rates and able to process said signal frame at its associated rate to produce a quality value for said associated rate without decoding said signal frame; a controller coupled to said rate quality estimators and able to select the rate whose quality value is best; a decoder coupled to said controller, said decoder able to decode said signal frame at said selected rate; and an erasure detection unit coupled to said decoder to determine whether said decoded signal frame has been decoded correctly.
Claim 7
Dependent Claim
120 words
A receiver to receive a signal frame encoded at a particular one of a set of rates, the receiver comprising: two or more rate quality estimators each having associated therewith a different one of said set of rates and able to process said signal frame at its associated rate to produce a quality value for said associated rate without decoding said signal frame; a controller coupled to said rate quality estimators and able to select the rate whose quality value is best; a decoder coupled to said controller, said decoder able to decode said signal frame at said selected rate; and an erasure detection unit coupled to said decoder to determine whether said decoded signal frame has been decoded correctly.
Claim 8
Independent Claim
92 words
A method for determining at which of a set of rates a signal frame was encoded, the method comprising: producing a rate quality value by processing said signal frame at one of said set of rates without decoding said signal frame; and if said rate quality value does not exceed a predetermined threshold or if an erasure criteria generated by decoding said frame at said one of said set of rates is not satisfied, producing another rate quality value by processing said signal frame at another one of said set of rates.
Claim 9
Independent Claim
92 words
A method for determining at which of a set of rates a signal frame was encoded, the method comprising: producing a rate quality value by processing said signal frame at one of said set of rates without decoding said signal frame; and if said rate quality value does not exceed a predetermined threshold or if an erasure criteria generated by decoding said frame at said one of said set of rates is not satisfied, producing another rate quality value by processing said signal frame at another one of said set of rates.
Claim 10
Dependent Claim
21 words
The method of claim 5 , further comprising: decoding said signal frame at said another one of said set of rates.
Claim 11
Independent Claim
