crypto technique..simple coding mechanism for given string

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.

用costas环实现载波同步。假设发送信号载波频率为3.563Mhz，本地初始频率为3.5628Mhz。程序中直接给出了环路滤波器的参数C1,C2。(this is synchoronization on time recovery basing on matlab)

这是一个用vc和matlab混合变成的例子，在两者环境下结合编成是很好的思路，有很大的应用前景，希望对大家有所帮助(with vc and mixed into Matlab example, in other circumstances combined organization is a good idea, a great prospect, we hope to help)
