Title:
MULTIUSER DETECTION WITH TARGETED ERROR CORRECTION CODING
Document Type and Number:
WIPO Patent Application WO2005125137
Kind Code:
A3
Abstract:
An error correction decoding (ECC) processing scheme is disclosed that reduces computational complexity normally associated with multiuser detection (e.g., TurboMUD) solutions, without causing degradation in quality of service or decreasing the total throughput. Error correction decoding algorithms are applied only to portions of the estimates that were affected by the immediately previous MUD (105) update process. Even though the MUD and/or ECC updating is targeted so as to reduce complexity of each iteration, all of the estimates are maintained and remain candidates for future updates. As such, there is no negative impact real-time or future performance. This targeting approach can be used in conjunction with many variations of MUD, including full-complexity or reduced complexity, and may include MUD (105) with confidence ordering or voting, and other techniques for facilitating efficient and effective MUD (105) processing.
