该程序主要用于LTE信道建模，支持8*8天线下的信道模型，包括说明文档(The program is mainly used for LTE channel modeling in support of 8* 8 channel model under the antenna, including documentation)

Occupancy Grid Mapping: using bayesian rules to update the grid probability of occupancy for only static coordinate (the probability describe the cell is occupied or not or unknown)

设计一个模拟信号（几个不同频率简谐信号之和，再加一个白噪声） 用不同的采样频率把信号离散（满足和不满足采样定理）， 画出信号波形； 分别作信号的谱分析（幅值）；对比采样频率的影响； 选用不同窗函数对同一个信号作谱分析，比较分析。(signal process using matlab)
