A new MAI control method in PMCAP/CDMA networks with hybrid ARQ type-II [mobile radio]

Multiple access interference (MAI) is a well-known bottleneck which limits the capacity of CDMA systems. A combined differentiated MAI control scheme for CDMA networks with hybrid ARQ type-II is proposed in this paper, taking into account that different trials of data packets have different error-correcting capabilities against MAI and largely different quantities. This method is shown to have significant improvement compared to traditional MAI control schemes.
