OFDM(正交频分复用)技术实际上是MCM(Multi-Carrier Modulation,多载波调制)的一种。其主要思想是,将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰(ICI)。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以

Single Carrier FDMA又称SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于OFDMA(主要用于下行),其最大的优势在于低峰值平均功率比(即PAPR)。本程序包括OFDMA,SC-FDE(单载波频域均衡)以及SC-FDMA程序,接收端采用经典的ZF和MMSE检测算法,程序短小精悍,相当经典,方便该领域的人学习与研究。

MSComm 控件提供下列两种处理通讯的方式:
事件驱动通讯是处理串行端口交互作用的一种非常有效的方法。在许多情况下,在事件发生时需要得到通知,例如,在 Carrier Detect (CD) 或 Request To Send (RTS) 线上一个字符到达或一个变化发生时。在这些情况下,可以利用 MSComm 控件的 OnComm 事件捕获并处理这些通讯事件。
