说明：  自己编制的直接相关函数，用来计算信号的自相关和互相关。(Prepare its own direct correlation function, used to calculate the signal autocorrelation and cross correlation.)

自由空间光通信系统在大气湍流信道下的3个主要性能指标分析，即平均误码率、中断概率和平均信道容量。其中大气湍流采用gamma-gamma湍流信道衰退模型。3个M文件为平均误码率与平均信噪比之间的关系(BER_SNR.m)，中断概率(OutageP.m)，以及平均信道容量与平均信噪比之间的关系（C_SNR.m）。程序可直接运行。(The analysis of 3 key performance indicators of Free-Space Optical communication system in atmospheric turbulent channel, namely the average bit error rate, outage probability and the average channel capacity. The atmospheric turbulence is modeled by the gamma-gamma turbulent channel fading model. Three M-files are the relationship between the average bit error rate and the the average SNR (BER_SNR.m), outage probability (OutageP.m), the relationship between the average channel capacity and the average SNR (C_SNR.m).The programs can run directly.)

基带传输： 欲传送的01比特流 + 码型变换（HDB3码） + 基带成型网络（采用升余弦滚降系统）+ 信道 + 码型反变换 + 01比特流。 (Baseband transmission: To send the 01 bit stream+ code type transformation (HDB3 code)+ base-band forming network (with raised cosine roll-off system)++ code based channel inverse transform+ 01 bit stream.)

认知中继网络包括一个主用户发射机和接收机，一个次用户发射机和接收机，以及一个放大转发中继。次用户发射机和中继从自然界获取能量。次用户共享主用户的频带进行数据传送，中继放大转发主用户发射机和次用户发射机的信号。次用户发射机和中继根据获取的能量和数据传送要求控制发射功率。功率控制建模为在能量因果约束、(Cognitive relay network includes a primary user transmitter and receiver, a secondary user transmitter and receiver, as well as an amplify and forward relay. Secondary user transmitter and relay obtain energy nature. Secondary users share a frequency band of the primary user data transmission, the relay amplification repeater primary user and a secondary user transmitter the transmitter signal. Secondary user transmitter and a relay and a data transfer request according to the energy obtained by controlling the transmission power. The power control is modeled as a causal constraints in energy,)
