Description: With the Wireless module, OPNET can model both
terrestrial and satellite radio systems. In this tutorial,
you will use Modeler and Wireless modeling to create a
radio network you will also observe variations in the
quality of received signal that results from radio noise
at the receiving node in a dynamic network topology.-With the Wireless module, OPNET can model both

Description: 就通信系统而言，涉及到有线信道及非卫星无线信道的问题时，信道不再可以看成为恒参信道，信号往往是通过未知信道传播，通常把这样的信道称为盲信道。 本源代码对盲信道的参数进行估计，利用matlab仿真，对做盲信道的工程人员有一定的借鉴价值。-On communications systems, related to non-cable channels and the issue of satellite radio channel, channel no longer can be seen as a channel Constant reference signal is often spread through unknown channels, usually channel such as the blind channel. Source code for the blind channel estimation of the parameters, the use of matlab simulation, on the blind channel to do the engineering staff from a certain value.

Description: Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions.We therefore find it timely to publish an up-to-date text on the subject
and at the same time include Galileo, the forthcoming European satellitebased
navigation system. Both GPS and Galileo belong to the category of Global
Navigation Satellite Systems (GNSS)

Description: 针对TCP (Transmission Control Protocol) 协议在高速卫星因特网中传输吞吐量低的问题, 提出了一种改
进TCP快速恢复的算法。该算法根据卫星信道由传输错误造成的分组丢失概率远大于由拥塞造成的分组丢失
概率的特点, 通过加快窗口的增长速度, 避免过早地进入拥塞避免阶段, 达到了提高TCP吞吐量的目的。通
过NS2软件模拟仿真了高速卫星因特网环境, 并对各个TCP版本和改进算法的仿真结果进行了比较和分析。
仿真结果表明, 改进算法的吞吐量比TCP2SACK提高了约10 , 比TCP2Reno提高了约30 。-A new algorithm is p roposed to imp rove the throughput of high speed satellite&internet network. In
satellite channels, most of lost package is due to transmission error instead of congestion. We can make some im2
p rovement on TCP (Transmission Control Protocol) fast recovery algorithm. Bymaking the window increase fas2
ter and not enter congestion avoidance too early. We imp rove the throughput of TCP. We use NS2 to simulate the
environment of satellite and internet network, and the results are compared. In simulation, about 10 through2
put in our algorithm is imp roved than TCP2SACK, and that is about 30 imp roved than TCP2Reno.
Key words: high speed satellite and internet network satellite channel transmission control p rotocol ( TCP)
