用C及ftp实现软件自动升级。通过在服务器端建立FTP服务,实现远程主机的文件更新. 软件启动过程连接服务器,获得软件文件更新列表(此步省略),进行本地文件更新 启动过程进行系统调用执行批处理文件ftpget.bat,调用方式system( "e:ftpget.bat" ) 文件ftpget.bat负责连接服务器下载所需文件,并完成文件的更新-C ftp software and automatic upgrades. Through the establishment of FTP server, remote mainframe file updates. Software startup process server connectivity, access to software updates list (this step is optional), a local paper started the process of updating system calls for the implementation of batch file ftpget.bat, call mode system ( "e : ftpget.bat") documents ftpget.bat for connecting servers to download the necessary documents, and complete the document update

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
