流水线设计是高速电路设计中的一个常用设计手段。如果某个设计的处理流程分为若干步骤，而且整个数据处理是“单流向”的，即没有反馈或者迭代运算，前一个步骤的输出是下一个步骤的输入，则可以考虑采用流水线设计方法来提高系统的工作频率。-see up

采用FPGA 来实现一个基于OFDM 技术 的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制 器包括：信道编码（Reed-Solomon 编码），交织，星座映射，FFT 和插 入循环前缀等模块。(FPGA to implement a baseband data based on OFDM technology in the communication system processing section, namely modem. Transmitter modulator includes: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and insert the cyclic prefix modules.)
