直线加速器twiss参数匹配，matlab模拟(linac twiss parameter matching, Matlab simulation)

ITU标准下的大气传播衰减计算程序，使用简单方便，只需要输入传播角度，高度，气候环境，即可计算大气传输损耗（不包括自由空间传播损耗）(According to the ITU standard, this program calculates the atmospheric loss. It is simple to use, you only have to input some parameters such as height, elevation angle, etc)

Matlab 航空工具箱 Aerospace Toolbox 2.2(Matlab Aerospace Toolbox 2.2)

This program simulates the transmission performance of BPSK under Additive White Gausian Noise (AWGN) environment.

In the computer science field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems.[1] Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover. Genetic algorithms find application in bioinformatics, phylogenetics, computational science, engineering, economics, chemistry, manufacturing, mathematics, physics, pharmacometrics and other fields.

The principle of space time block coding with 2 transmit antenna and one receive antenna is explained in the post on Alamouti STBC. With two receive antenna’s the system can be modeled as shown in the figure below

不知道怎么弄的 你先给我开开吧 我急着用呢 好不好啊(SDAFSDFGSGQWRAEFSDFDSFGGSDF)

用于实现OFDM系统下的信道估计并有波形输出(designed for OFDM based on 16QAM)

完成M=4的DPSK通信系统的蒙特卡洛仿真，信号波形为snr2ps(snr_in_dB) 求出以dB为单位的给定信噪比的比特误码率和符号误码率.(Completion of M = 4 of the DPSK communication system Monte Carlo simulation, the signal waveform is snr2ps (snr_in_dB) calculated in units of dB signal to noise ratio for a given bit error rate and symbol error rate.)
