: 正交频分复用( O F D M) 是第四代移动通信的核心技术。 该文首先简要介绍了O F D M基本原理, 重点研究了理想同步情
况下, 保护时隙( c P )和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对O F D M系统性能的影响。 在给出O F DM系
统模型的基础上, 用 MAT L A B语言实现了整个系统的计算机仿真并给出参考设计程序。 最后给出在不同的信道条件下, 保
护时隙、 信道估计方法对 OF DM系统误码率影响的比较曲线, 得出了较理想的结论。

modbusgw-0.1.tar
MODBUS programEach instance of modbusgw acts a master to a modbus serial network. Currently each
instance of modbusgw will only support one modbus serial network (future revisions will support
multiple networks in a single gateway for now, it is necessary to start multiple instances).

check_valve_motion
排氣閥門的UDF,裏頭有寫著在如何的壓力底下排氣閥門會開啟,當壓力未達到時排氣閥門將會關閉(Exhaust valve UDF, inside there that says how the pressure beneath the exhaust valve opens when the pressure does not reach the exhaust valve will be closed)
