Abstract
Aspects of a method and system for an improved cellular diversity receiver are described. Aspects of the system may include circuitry that enables generation of an initially decoded output bit sequence by a first frame process for a received bit sequence for a plurality of received multipath signals. The first frame process may utilize redundancy based decoding, which imposes at least one physical constraint during the decoding, which may be performed by a decoding algorithm.
Claims20
A method for signal processing, the method comprising:
- performing by one or more circuits a multi-layer decoding process comprising:
- generating, using a frame process, a first decoded output bit sequence from a received bit sequence for a plurality of received multipath signals, wherein the received bit sequence is derived from the plurality of received multipath signals using a first burst process iteration of a burst process, and wherein the burst process includes decoding one or more groups of encoded bits included within a frame;
- if said first decoded output bit sequence fails verification, feeding back the first decoded output bit sequence;
- and
- processing at least a portion of the fed-back first decoded output bit sequence by a second burst process iteration of the burst process, wherein the second burst process iteration is based on using a gradient search approach applied to a received signal and an estimate signal.
