First Claim
Patent Images
1. A method for wireless communications, comprising:
- initiating a decoding procedure to decode a received signal in a wireless system;
evaluating a first criterion;
terminating the decoding procedure early if the first criterion is satisfied;
evaluating a second criterion if the first criterion is not satisfied;
terminating the decoding procedure early if the second criterion is satisfied;
evaluating a third criterion if the second criterion is not satisfied; and
terminating the decoding procedure early if the third criterion is satisfied.

Abstract
Certain embodiments provide methods that may allow for improvements in performance and power consumption by terminating the turbo decoding process early when one of at least two test criterion is satisfied in communications systems, including UMTS, WCDMA, and TD-DCMA.
