“…Several methods have been proposed to deal with interference noises cancellations problem, such as successive interference cancellation (SIC) [5], [6] and parallel interference cancellation (PIC) [7], [8]. Both of them were originally devised to RF receivers to eliminate unmatched signals and spurious interference noises within the received signal+noises.…”

In this paper, we propose a recursive interference cancellation (RIC) scheme over optical coding access network coder/decoders (codecs). The novel-designed interference noises canceller is structured over arrayed-waveguide gratings (AWGs). By recursively following the recoding, subtraction, and decoding processes, the reconfigured AWG codecs will largely suppress optical interference noises to successfully recover target user data bits. Numerical evaluations are taken to illustrate the RIC processes to compare different recursive rounds and code weights distribution to the SNR performance of target data bit decoding.

“…Because this program must constantly order the new succession sort of multi-user to priority process the maximum power user [4], so any detection error on any detection level would increase MAI and lead detection error diffusion, then severely affect the precision of the subsequent levels [5]. As an optimal estimation algorithm under the linear minimum mean square error (MMSE) criterion [6], the Kalman algorithm can not only make on-line synchronous unbiased estimation of the unknown noise statistics characteristics in DS-CDMA system while conducting state filtering, but also build a state space model for the MUD processing, so as to use optimal filter to adaptive estimate the optimal decision vector [7].…”

The multiuser detection precision of successive interference cancellation (SIC) detector is always affected by the decision error diffusion. This paper focuses on the SIC algorithm of direct sequence spread spectrum code division multiple access (DS-CDMA) system with strong multiple access interference (MAI) and inter symbol interference (ISI). A blind adaptive Kalman-SIC multiuser detection (MUD) algorithm is proposed in this paper. This algorithm can totally track the time-varying channel, minimize the detection error diffusion, and thus effectively suppress MAI and ISI. Simulation results show that the blind adaptive Kalman-SIC algorithm is of better tracking ability, convergence and detection precision. 

“…However, both face the problem of a noise enhancement and the requirement of channel estimates at the receiver. The successive interference cancellation [10] technique in the nonlinear category of detectors faces the problem of error propagation, whereas the performance of Parallel interference cancellation (PIC) [11] heavily depends on the initial bit estimates. Recently, there has been increased interest in using evolutionary techniques for the MUD problem, e.g., the Genetic algorithm (GA) [12] , ant colony optimization [13] , Particle swarm optimization (PSO) [14,15] , and Honeybees Mating Optimization [16] .…”
