多径信道下可有效提高频偏估计性能
文章对几种常用的基于循环前缀(CP)的最大似然同步算法进行了分析，并对其频偏估计方差进行了比较；同
时针对基于CP 的同步算法在多径衰落信道下性能较差的情况，提出了一种改进的CP 同步算法并进行了仿真，结果表明相比
于原ML 算法，文中算法在多径信道下可有效提高频偏估计性能。(】This paper does some research on multiple maximum-likelihood (ML) algorithms based on cyclic prefix
(CP) and compares variances of frequency-offset estimation After the analysis of the bad performance of CP based
algorithms in multi-path fading channels, an improved CP algorithm is proposed and the simulation shows that this
algorithm can improve its performance effectively in multi-path fading channels.)

BCH(15,5,7)a communication system consists of binary source, 3 error-correcting BCH code of length 15 over GF(24) (i.e, BCH (15,5,7 code), the primitive polynomial is p(x)=1+x+x4), BPSK modulator, AWGN channel, coherent demodulator, decoder (either BMA or EA could be utilized to solve the error locator polynomial) and sink. Simulate and draw its error performance with and without BCH coding, together with the theoretical no-coding curve, i.e. two BER-EbNo curves.(a communication system consists of binary source, 3 error-correcting BCH code of length 15 over GF(24) (i.e, BCH (15,5,7 code), the primitive polynomial is p(x)=1+x+x4), BPSK modulator, AWGN channel, coherent demodulator, decoder (either BMA or EA could be utilized to solve the error locator polynomial) and sink.

sliding mode:In this project, a sliding mode controller is designed to a linear plant with non-linear dis-
turbances. The performance of the designed controller is then veri ed via simulation using
MATLAB and Simulink. Then, the sign function in the designed controller will be replaced
by a sat function, and the performance of the new controller will be investigated. Finally,
some conclusion remarks will be made according to the simulation results.
