ofdm仿真
说明: OFDM即正交频分复用技术,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)

multiuser
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.
