- 信道均衡技术（Channel equalization）是指为了提高衰落信道中的通信系统的传输性能而采取的一种抗衰落措施。它主要是为了消除或者是减弱宽带通信时的多径时延带来的码间串扰（ISI）问题。 其机理是对信道或整个传输系统特性进行补偿，针对信道恒参或变参特性，数据速率大小不同，均衡有多种结构方式。大体上分为两大类：线性与非线性均衡。对于带通信道的均衡较为困难，一般都是待接收端解调后在基带进行均衡，因此基带均衡技术有广泛应用。在实际中一般是加入自适应滤波器来实现信道均衡。-Equaliz

Xmodem
- XMODEM协议是一种串口通信中广泛用到的异步文件传输协议。分为标准Xmodem和1k-Xmodem两种，前者以128字节块的形式传输数据，后者字节块为1k即1024字节，并且每个块都使用一个校验和过程来进行错误检测。在校验过程中如果接收方关于一个块的校验和与它在发送方的校验和相同时，接收方就向发送方发送一个确认字节(ACK)。由于Xmodem需要对每个块都进行认可，这将导致性能有所下降，特别是延时比较长的场合，这种协议显得效率更低。(XMODEM protocol is a widely us
