Abstract
A new divide-and-conquer scheme has been proposed with adaptive modulation in CDMA system to improve the spectrum efficiency of the wireless communication system. The proposed method results in increase in average throughput achieved and simultaneously decrease in the outage probability of the system when the user density is high. The proposed scheme is compared with the existing algorithms and the advantage of the scheme is evident from the results obtained.
