  • Understanding+Optical+Communications

    The use of light to send messages is not new. Fires were used for signaling in biblical times, smoke signals have been used for thousands of years and flashing lights have been used to communicate between warships at sea since the days of Lord Nelson. The idea of using glass fibre to carry an optica ...

  • DCT变换

    将图片转化为double数据类型,再利用T=dctmtx(8)建立一个8*8的DCT变换矩阵。将图片分割为8*8的小块,分别对小块进行各自的DCT变换。变换的矩阵可调用函数dctmtx,得到余弦基函数作为变换基T。T*B*T’是变换的操作,得到DCT变换系数矩阵。接着按照实验要求,将 DCT 系数矩阵中值小于给定阈值的元素置为 0。这样就完成了DCT ...

  • 伯努利装错信封问题-综合[难]

    题目描述     某人写了n封信,同时为每一封信写1个信封,共n个信封。如果把所有的信都装错了信封,问共有多少种?(这是组合数学中有名的错位问题。著名数学家伯努利(Bernoulli)曾最先考虑此题。后来,欧拉对此题产生了兴趣,称此题是“组合理论的一个妙题”,独立地解出了此题)  &nbsp ...
