Applying probability control to cognitive CDMA communication system for anti-interference

The technique of cognitive code division multiple access (CCDMA) communication is attracting more and more attention. The existing researches use power control to suppress the interference, but it is not always optimal. Probability control is a recently introduced method that allows better mitigation of multiple access interference in CCDMA networks. In this reported work, probability control is applied to CCDMA for anti-interference. It can be concluded that the performance reflected by the signal-to-noise-plus-interference ratio resulting from probability control is better than the one resulting from power control by numerical simulation results.
