image proccesing improved by using spatial filtering

功放预失真模型，matlab实现，用神经网络算法(power amplifier predistortion )

matlab数据分析的经典算法，可以用于数据分析(matlab data analysis of the classic algorithms, can be used for data analysis)

一种改进的基于模拟退火的粒子群算法(SimPSO)。将模拟退火算法的思想引入粒子群算法中,并对更新公式进行优化(An improved particle swarm optimization algorithm based on simulated annealing (SimPSO). The simulated annealing algorithm is introduced into the particle swarm optimization algorithm, and the updating formula is optimized.)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

说明：  将观测到的原始GPS数据，使用matlab每天求一个平均值，代码中含有实例文件！(Assistant will observe the original GPS data, use matlab to calculate an average value every day, the code contains the instance file!)
