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

AODV 协议
特设上需求距离矢量路由 (AODV),这种点对点网络的运行算法。每个作为一个专门的路由器,移动主机运行和路线得到所需 (即,点播) 很少或不依赖于定期的广告。路由算法是非常适合作为根据用户希望利用需要一个动态的自我-起始网络,ad hoc 网络。AODV 提供无环路的路由,甚至同时修复断开的链接。因为议定书 》不需要全球周期性路由广告,对可用钼-的总体带宽需求胆汁节点远远低于在这些协议中,做需要这类广告。
