In this code, the BER performance of a system which uses sparse channel estimation is compared with a system which uses LSE channel estimation. It is shown that using sparse technique improves the performance of the system

encoding and decoding based on arithmatic operators may be used for compression

gravitational search algorithm 1

it is MRC technique uesed in lte MIMO lte

srukf 代码，经试验可用，可以解决ukf在模型不匹配时出现的发散或者不稳定等问题(srukf code, used by the pilot, can solve ukf model mismatch occurs when the divergence or instability problems)

用来计算十字交叉点的中心位置,可以达到亚像素精度，在三维重建中经常会在物体表面做标志，本算法用于计算十字标记中心(to calculate the center of a cross image)

本文档是MATLAB详细的教程课件，对MATLAB初学者来说是很好的一部教材。对大家肯定会有很大的帮助的。(This document is a detailed tutorial MATLAB software for beginners MATLAB is a very good teaching. I am sure you will be on a lot of help.)

最后的测试程序，得出文本检索的正确率和召回率(In the end, the cosine similarity of texts is used to measure the similarity between the query and documents. The data comparison indicates that this algorithm has well experimental results. Moreover, it gets the advantage over the classic LSA retrieval algorithm in precision and operational efficiency.)
