误码率

The symbol-error-rate performance is analyzed for a two-user amplify-and-forward cooperative communication system when the relay is movable and immoveable.

在中继端运动与静止两种情况下分析了一个两用户放大转发协同通信系统的误码率(symbol-error-rate，SER)性能。

A flexible buffer was placed between the over-sampler and DPLL.Not only was 10bits data recovery implemented,but also the frequency of sampling clock was reduced to 2.5 times of the data frequency.The phase verification for 10bit parallel data by DPLL increases the accuracy rate of judgment and improves the bit error rate.

通过在过采样电路和数字锁相环之间增加弹性缓冲电路，在实现10bit数据恢复的同时，使采样时钟频率减小为数据频率的2.5倍，DPLL同时对10bit并行的数据进行相位检测判断，提高了判断的正确率，使数据传输的误码率得到改善。

However, if we used BER (the 'loosest'), we could also represent it with three strings that would be concatenated:"Crypto","","Interop".

但是，如果我们用误码率，我们也可以代表三，将被连接字符串是：&加密&，&&，&互操作&。

The relation of single user detection and multiuser detection is also analyzed.

与单用户检测方法相比其误码率有相当的改进。
