MPSK
This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

sun_position
一个相当好用的matlab函数,由美国国家可再生能源实验室科研人员设计,可以计算太阳的直射维度和方位角。只要输入时间、观测地点即可。 (This algorithm is based on numerical approximation of the exact equations.
The authors of the original paper state that this algorithm should be
precise at+/- 0.0003 degrees. I have compared it to NOAA solar table
(http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and to USNO solar
table (http://aa.usno.navy.mil/data/docs/AltAz.html) and found very good
correspondance (up to the precision of those tables), except for large
zenith angle, where the refraction by the atmosphere is significant
(difference of about 1 degree). Note that in this code the correction
for refraction in the atmosphere as been implemented for a temperature
of 10C (283 kelvins) and a pressure of 1010 mbar. See the subfunction
un_topocentric_zenith_angle_calculation� for a possible modification
to explicitely model the effect of temperature and pressure as describe
in Reda & Andreas (2003). )

广义最小二乘的算法结构,广义最小二乘递推的每一步用两步递推算法,先把噪声参数和模型参数均给个初值,然后第一步先假设噪声参数已知,用最小二乘估计出模型参数,第二步再用最新的模型参数来估计噪声参数,如此循环直到辨识精度达到指定要求或者可用数据用完为止(Generalized least squares algorithm structure, generalized recursive least squares every step of the two-step recursive algorithm, first noise parameters and model parameters to the initial value, then the first step is to assume that the noise parameters are known, with the smallestsquares to estimate the model parameters, and the second step, and then the latest model parameters to estimate the noise parameters, and so on until the identification accuracy specified requirements or available data is used up)

Monte_Carlo_simulation_cool
说明: 蒙特卡罗模拟随机数是最好的方式,本程序设计在552nm脉冲后,再一左一右的657nm冷却脉冲,测试激发达到100 的概率,尤其考查蓝、绿及近红外波段(MATLAB 6.5 Monte Carlo simulation cool3.m
This simulation cycles "num" number of atoms "steps" times, with a cooling sequence of
a 657 nm cooling pulse from the right, then a 657 nm cooling pulse from the left,
followed by a 552 nm quenching pulse. Then the sequence is repeated with cooling
pluses first incident from the left. Switching the pulse direction
order helps maintain symmetery in the resultant velocity distribution.
The probability of quenching the excited state is no longer 100 , it is "percent"
Random blue, IR, and green photon recoil kicks have been included in the simulation due to the
quenching.
