本文针对并行干扰抵消检测器的不足之处，提出了改进的并行干扰抵消检测算法——基于多项式展开的并行干扰抵消多用户检测算法。该算法将多项式展开检测器作为并行干扰抵消检测器第一级的数据估计值，以提高检测可靠性。通过仿真实验，首先验证了多项式展开检测器的性能。然后比较改进算法与传统检测器的性能，验证改进算法的系统性能得到明显改善；并与并行干扰抵消检测器、解相关检测器和MMSE检测器相比较，验
证得到该改进算法的性能也有不同程度的改善。
(this paper discusses the principle and performance of the
conventional detector and the parallel interference cancellation(PIC)detector
separately.Since the conventional detector take MAI only as the background noise without considering the existence of the other users,the existence of MAI has a significant impact on the performance of CDMA systems.Each stage of PIC detector utilizes the data estimates of the initial or previous stage,produces a new set of MAI estimates,and then subtracts out all of the MAI for each user in parallel.Through Monte Carlo simulation in different scenarios,the results illustrate the influence of MAI in conventional CDMA ystems.Theexperimental results show PIC detector can effectively eliminate MAI andimprove the system BER.

Pareto-design-of-Load-Frequency-Control-for-inter
In this study, it is tried to employ a state-of-the-art multi-objective uniform-diversity genetic algorithm
(MUGA) for Pareto optimization of PI/PID controllers in Load Frequency Control (LFC) of power systems.
At fi rst, multi objective optimization of a linear non-reheat two-area interconnected power system is
conducted with respect to three confl icting objective functions. Gains of PI and PID controllers are con-
sidered as design variables while the objective functions are Integral Time multiply Absolute Error (ITAE),
