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

多线程,多接收模式串口类 LsComm 之二相关文档
多线程,多接收模式串口类LsComm 作者:Liu_sir
所以参照Delphi中的SpComm设计了一个类CComPort,对CSerialPort进行了2次封装,主要目的是简化串口的使用.使其用简单的代码就可以完成串口通讯的过程.并提供了一个Demo程序演示了CComPort的使用
多线程,多接收模式串口类 LsComm 之二 作者:liu_sir
实现了一个简洁易用的多线程串行通讯接口,可以切换查询和自动接收模式,进行对串口数据收发-Multi-threaded, multi-category serial receive mode LsComm documentation bis multi-threaded, multi-category serial receive mode LsComm Author: Liu_sir Therefore, in light of Delphi SPComm designed a category CComPort, on a 2 times CSerialPort package The main purpose is to simplify the use of serial port. its simple code to complete the process of serial communication. and provided a Demo program CComPort demonstrated the use of multi-threaded, multi-mode receiver serial-type bis LsComm Author: liu_sir implements a simple-to-use multi-threaded serial communication interface, you can switch query and automatically receive mode and proceed to the serial data transceiver

本文讨论一个设计团队要考虑的具体问题…
This paper addresses the specific issues that a design team will have to consider in
creating solutions for embedded devices. Starting with a generic architecture, issues
regarding the creation of the hardware target and concomitant software are presented.
Bluetooth system operation is then briefly discussed with the intention of taking into
account the unique needs of a wireless connection in structuring the application software.
Implementation issues are then discussed and closely followed up with development ideas that are designed to not only contain the project burn rate but also to get the product
to market in as short a time as possible. -
