1. Preview of simulation diagram of algorithm part

Several main modules involved in this system , There are several modules as follows ：

A. Simulation Flow： Simulation process

B. Initialization： initialization

C. Mobility Model： Move the model

D. Traffic Model： Traffic model

E. Propagation Model： Signal transmission model

F. Multipath Model： Multipath model

G. SINR Calculation：SINR Value calculation model

H. Link Level Quality Estimation： Link level quality evaluation

I. Scheduling： System scheduling

according to Path Loss Model: The path loss between a macro BS and a MS is characterized can be calculated as follows:

    here ,R The value of indicates the distance from sending to receiving , Unit is “ rice ”,Low Is the attenuation of the outdoor wall , Usually this value is 10dB perhaps 20dB.

    The following is MATLAB In the simulation , The simulation results are as follows ：

Calculation method of signal to interference noise ratio of the system , According to the formula in the paper ：

namely SINR Is the received power of the signal /（ Interference power + Noise power ）

The simulation results are as follows ：

    Scheduling model , Include RR Dispatch and PF Dispatch , here , It mainly uses PF Scheduling analysis ; Mainly through MATLAB Studied PF Scheduling model .

PF The throughput is obtained after scheduling .

PF The calculation formula of scheduling is ：

be based on Femtocell Simulation of spectrum sensing algorithm
