windows i/o模型中著名的重叠i/o模型，在windows平台并发不是很大的情况下，还是很好的。-windows i / o model of the famous overlapping i / o model the windows platform is not very complicated circumstances, or very good.

ofdm加窗前后的对比频谱图，以及循环前后缀重叠与不重叠两种情况的对比，最后给出了误码率的计算。-ofdm added after the contrast spectrum window, and the cycle before the suffix overlap and contrast the two cases do not overlap Finally, the bit error rate calculation.

由于WINCE不支持重叠I/O操作，因此可分别用单独的线程去读写串口，通过多线程来模拟重叠操作[4]-WINCE does not support as a result of overlapping I/O operation, it can be a separate thread to read and write serial port, through multi-threading to simulate the overlapping of operations [4]

分段品均周期图方法 用Matlab编程仿真实现 有重叠分段和不重叠分段两种-Commodities are segmented periodogram method simulation using Matlab programming with overlapping sections and two kinds of non-overlapping segments
