本文件算出闭合曲线图形的面积是根据像素点来的(Closed curves calculated in this document is based on the size of graphics to the pixel)

An ad-hoc network with a sender, a destination and a third station act- ing as a relay is analysed. The channels are modelled containing thermal noise, Rayleigh fading and path loss. Di® erent combining methods and di- versity protocols are compared. The amplify and forward protocol shows a better performance than the decode and forward protocol, unless an error correcting code is simulated. To combine the incoming signals the chan- nel quality should be estimated as well as possible. Information about the average quality shows nice bene¯ ts, and a rough approximation about the variation of the channel quality increases the performance even more. What- ever combination of diversity protocol and combining method is used second level diversity is observed. The relative distances between the relay and the stations has a large e® ect on the performance.

这个压缩包里面是极化码的SCL方案的仿真 可以设置不同的码长和信噪比 并且可以选择高斯信道和擦除信道这两种信道(This program simulate the performance of SC-list scheme of polar code. You can choose different SNR and code length.You also can choose two type of channels.)

program that the process can make word also thin
