調和搜尋演算法(Harmony Search HS)是將樂團演奏表現調整至最協調且美妙的現象引用到最佳化演算系統當中，而發展出一套全新的啟發式演算法(Reconcile the search algorithm (Harmony Search HS) is the Orchestra performance of coordinated and adjusted to the most wonderful reference to the best of the phenomenon Calculus systems are, and develop a new heuristic algorithm)

Several signed LMS based adaptive filters, which are computationally superior having multiplier free weight update loops are proposed for noise cancellation in the ECG signal. The adaptive filters

生成一个规则LDPC码的教研矩阵H，其行数(越大越好)为列数的一半，行重为6，列重为3，任意两行没有围长为4的圈 使用方法：H=HGrandom2(m,n)。m表示行数，n表示列数(rules of a generation of research LDPC matrix H, its (larger the better) half of the series, re-6, series of three, two arbitrary line is not girth of the ring used four methods : H = HGrandom2 (m, n). Said a few m, n Columns)
