Cognitive code division multiple access (CCDMA) systems commonly use power control to reduce the interference between the users. But the power control is not always optimal. Probability control is a recently introduced method that allows better mitigation of multiple access interference in CCDMA networks. In this paper, we apply the probability control to CCDMA system. It was found that the performance reflected by the signal to noise plus interference ratio (SINR) resulting from probability control is better than the one resulting from power control by some simulation results.
