Interference cancellation in multirate DS/CDMA systems
This paper presents multistage interference cancellation (IC) schemes for the uplink of multirate directsequence code division multiple access (DS/CDMA) systems.The performance is evaluated both analytically and via computer simulations for two multiple data rate schemes, mixed modulation and parallel channels, assuming flat Rayleigh fading and multipath environments. Introduction It is anticip...
متن کاملInterference cancellation in multi-cell CDMA systems
Multiple access and inter-symbol interference of CDMA systems within a cell make single user detection error prone. Perturbation method of multi-user detection (MUD) can correct this. In addition to the single cell interference there is adjacent cell interference (ACI), which can be reduced by a set of new codes with interference reduction window (IRW) and exclusive even/odd code assignment to ...
متن کاملAdaptive Blind Interference Cancellation in Cdma Systems
Multiuser CDMA communication systems experience multiple access interference as well as multipath distortions and require some interference cancellation scheme at the receiver. While blind multiuser receivers have received considerable attention, adaptive versions are often limited to the no multipath case. In this paper, the receiver’s output variance is minimized subject to appropriate constr...
متن کاملInterference Mitigation Using Successive Interference Cancellation in Optical CDMA Systems
Performance of optical code division multiple access (O-CDMA) system is influenced by multiple access interference (MAI) resulted from the overlapping between the users. To overcome this problem, successive interference cancellation (SIC) scheme is applied to O-CDMA systems. In this paper we apply successive interference cancellation technique to a spectral amplitude coding (SAC) system that us...
متن کاملImproved parallel interference cancellation for CDMA
This paper introduces an improved nonlinear parallel interference cancellation scheme for code-division multiple access (CDMA) that significantly reduces the degrading effect on the desired user of interference from the other users that share the channel. The implementation complexity of the scheme is linear in the number of users and operates on the fact that parallel processing simultaneously...
