dbpsk调制解调程序
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

sim 文件系统In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.-sim file system In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements.

NS2所有awk脚本文件
应用背景awk脚本从测井数据处理是非常好的（跟踪文件），我们可以从NS2。如果你想进程的跟踪文件手动和容易得到的结果。关键技术对于NS2仿真实例，首先就要写一个Tcl脚本，通过终端。TCL是一个跟踪文件输出的进一步处理通过awk脚本来获取网络性能 ；如吞吐量，平均端到端时延，抖动，丢包率，总收到的数据包，总的数据包发送 ； ；O等，
