Patent ID: 8687744

Claim:
A method for signal processing, the method comprising: performing by one or more circuits and/or processors: generating a first decoded output bit sequence utilizing a first decoding algorithm in a frame process, wherein said first decoded output bit sequence is generated from a received bit sequence for a plurality of received multipath signals; when said first decoded output bit sequence fails verification, generating by said frame process, a second decoded output bit sequence from said received bit sequence for said plurality of received multipath signals utilizing a second decoding algorithm, wherein said second decoding algorithm comprises a redundancy-based decoding that imposes at least one physical constraint; feeding back information decoded in said frame process; and processing the information by a burst process that comprises decoding one or more groups of encoded bits included within a frame, wherein the burst process includes a first burst process iteration and a second burst process iteration, and the second burst process iteration is based on using a gradient search approach to determine a minimal distance H between a received signal and an estimate signal.
