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

在许多软件系统中，表格控件在对数据进行浏 览、编辑等操作方面都有良好表现。遗憾的是，Visual C++并没有提供直接支持表格操作的通用控制类。不 过，我们可以通过注册VisualC++5.O的ActiveX 控件中的Microsoft FlexGrid Control,version5.0 控件并添加到项目中来实现对表格的显示及操作。下 面将结合具体实例，介绍如何在对话框中加入表格控 件并实现对表格数据的显示、修改和保存。文中程序 是在中文WindowsNT4.0环境下，用VisualC++・5.0 编写的。 -In many software systems, forms control in the data view, edit and operational aspects such as good performance. Unfortunately, Visual C++ does not provide direct support to form a common operational control class. However, we can register VisualC++5. O The ActiveX controls in the Microsoft FlexGrid Control, version5.0 control and add to the project to achieve the right form of display and operation. Below with specific examples on how to add form controls in the dialog box and to achieve the display of tabular data, modify and save. This paper program is in the Chinese WindowsNT4.0 environment, using VisualC++ ・ 5.0 prepared.
