qpsksystem_SJSU_mdl
QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

可以看到
变步长未必会需要更长的时间
因为它是一种自适应的方式
如果某阶段情况理想的话
就会用最大步长来做
那就会很快
(can see variable step may not need a longer period of time because it is an adaptive way if a certain phase of the the ideal would be the greatest step will be to do it quickly)

TSP
TSP问题是经典的寻优问题 也是人工智能里一个重要的问题 我编写的程序主要是用蚁群算法来解决这个问题。蚁群算法是人工智能里用来寻优的重要算法 由于蚁群算法的优点使得TSP问题能够实现。
(The TSP problem is a classical optimization problem is also an important problem in artificial intelligence programs written in my main is to use ant colony algorithm to solve the problem. Ant colony algorithm is used in artificial intelligence (ai) optimization algorithm is important due to the advantages of ant colony algorithm can achieve the TSP problem.)
