Abstract

The present invention discloses an intelligent multi-user detecting method for immune colon belonging to the technical field of artificial intelligence, which aims to remove distance effect and multiplex access interference of prior arts to enhance distance effect resistance, multiplex access interference resistance and noise interference resistance and reduce calculating complexity compared with optimal multi-user detections and includes following fulfillment steps: (1) Initializing, setting arithmetic termination terms, specifying arithmetic operating parameters and randomly creating initial antibody clusters; (2) Calculating compatibility of the antibody; (3) Judging arithmetic terminal terms; (4) Conducting colon death to antibody clusters; (5) Fulfilling colon amplification to antibody clusters after antibody death; (6) Carrying out clone variation to antibody clusters after colon amplification; (7) Calculating antibody cluster compatibility after colon variation; (8) Realizing antibody cluster colon selection after colon variation and returning step (3). The method can solve problems of multi-user detection in CDMA systems of 3G mobile communications.

Description

Technical field [0001] The invention belongs to the field of artificial intelligence technology, relates to an application of artificial intelligence technology in the field of communication technology, and specifically relates to an intelligent multi-user detection method of immune cloning. This method can be used to solve the multi-user detection problem in the third-generation mobile communication code division multiple access system, that is, the CDMA system. Background technique [0002] With the gradual maturity of the third-generation mobile communication technology, the standardization and development of 3G has entered a substantive stage. Overcoming the shortcomings of the existing 3G technology has become an important task for many research institutions. As the core technology of 3G, CDMA meets the bandwidth requirements of modern wireless communication through spectrum multiplexing and high spectrum efficiency multiple access technology, but it has problems such as dis...
