Parallel multiple access interference cancellation in optical DS-CDMA systems
This paper investigates the Parallel Interference Cancellation technique in Direct Sequence Optical Code Division Multiple Access (DS-OCDMA) system. In the proposed system, the estimated interference is removed from the received signal. We have developped a new approach to obtain the analytical expression of error probability in chip synchronous case, for Optical Orthogonal Codes (OOC). We have...
متن کاملNew Receiver Architecture Based on Optical Parallel Interference Cancellation for the Optical CDMA
Optical Code Division Multiple Access (OCDMA) is considered as the strongest candidates for the future high speed optical networks due to the large bandwidth offered by the system, Based on the vast amount of bandwidth, OCDMA systems have received much attention in fiber optic Local Area Networks where the traffic is typically bursty. However, Multiple Access Interference (MAI), which is origin...
متن کاملHYBRID INTERFERENCE CANCELLATION RECEIVER FOR DS-CDMA SYSTEMS L.Nithyanandan and P.Dananjayan
In a CDMA system, the performance of channel matched filter receivers are limited by the presence of multi-user interference. Hence receivers must be capable of suppressing these interferences. Interference suppression or interference cancellation works by subtracting the interfering users from the received signal, thus allowing an improved error rate for the user of interest. In this paper a h...
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 کاملAnalytical BER Computation for MC CDMA System with Iterative HIC Receiver
The existing mobile communication system suffer from problems like frequency selective fading and multi-path signals, multiple access interference due to imperfect nonorthogonal codes and narrow band interference due to coexisting systems. Multi-carrier Code Division Multiple Access (MC-CDMA) technique can combat these problems efficiently owing to its inherent properties. The objective of this...
