SYMPCHUNK sets the number of symbols demodulated at once with a constant carrier frequency and symbol timing offset. This is a fundamental decoder parameter that establishes its carrier and symbol timing tracking bandwidth. Set it too low and the demodulator can"t accurately determine carrier frequency and symbol timing on a noisy signal. Set it too high and the demodulator may not be able to track large symbol rate offsets caused by Doppler shift and/or A/D or spacecraft clock errors. Or it might have trouble tracking high rates of change in the carrier frequency due to Doppler acceleration.The current value of SYMPCHUNK is 4*N1 = 512, where N1 = 128 is the order of the convolutional interleaver. 512 symbols is 512 milliseconds at 1000 symbols/sec, giving a frequency/time determination SNR that is 10*log10(512) = 27 dB greater than the Es/N0, not counti

动态源路由协议（DSR）是一种简单而高效的路由协议专门设计用于在多跳无线ad hoc移动节点的网络。 DSR允许网络是完全自组织和自配置，而无需对任何现有的网络基础设施或施用。DSR已经被无数的团体执行，并将其部署在多个测试平台。使用DSR协议的网络已连接到Internet。 DSR可以与移动IP互操作，并使用移动IP和DSR节点的无线局域网，蜂窝数据服务和DSR移动ad hoc网络之间的无缝已迁移。该协议是由“路由发现”和“路由维护”两大机制，共同努力，允许节点发现和维护路由，在ad hoc网络的任意目的地。该协议的各个方面按需完全运作，允许DSR路由包开销自动缩放到只需要作出反应的变化，目前正在使用的路由。该协议允许多个路由至任何目的地，并允许每个发送来选择和控制路由选择的分组，例如用于负载平衡或用于增加鲁棒性所使用的路由。在DSR协议的其他优点包括易于保证无环路的路由，用于支持包括单向链路，使用路由只有“软状态”，并非常迅速恢复网络时，在网络更改路线。该DSR协议设计主要是为高达约200节点的移动ad hoc网络，旨在与甚至是非常高的流动性速率工作。
