当前工程上广泛采用了一种高效滤波器，即CIC（cascaded integrator-comb filter）将其作为第一级来实现抽取、低通滤波。第二级再用一个普通的FIR滤波器就实现使后端设备工作在较低的频率下且硬件花销少、功耗也很低。(Widely used in the current project, a highly efficient filter, that is, CIC (cascaded integrator-comb filter) as the first level to achieve the extraction, low-pass filter. An ordinary second-class and then the realization of the FIR filter so that the work of the back-end equipment at a lower frequency and spending less hardware, power consumption is very low.)

A lot of codes in matlab the handbook of tracking posicion. Very well codes.

认知无线电中频谱感知的实现问题，这是一篇英文文献，里面很详细的论述了频谱感知中遇到的问题，特别是在能量感知中的问题，适合刚开始研究频谱感知的爱好者或者研究者学习。(The issue of spectrum sensing in CR, before simulation, you must know the theory of sensing and test statistics.)

仿真采用Erlang B模型，此仿真考虑用户呼叫时，若无空闲信道则被阻塞的情况。对话务量和阻塞率进行仿真(Simulation using Erlang B model, consider the user calls this simulation, the channel was idle without congestion. Blocking rate for traffic simulation )
