诺亚短信控件 ~~~~~~~~~~~~ 本控件支持大部分的手机和GSM工业模块,通过计算机串口或USB转串口可以 实现手机或GSM工业模块短信收发，电话簿管理，拨打电话等工作. 一、主要特点: ========== 1.数据收发可靠，经过大量短信收发的检验 2.可以同时处理短信发送，和短信接收工作 3.多个操作可以同时进行，不会产生数据遗失 4.允许读取所有电话簿,读取所有短信，读取短信数量和容量 5

通信系统仿真大作业，卷积码编码，QPSK调制，接收端维特比软判决。程序正确。-Communication system simulation a large operation, convolution coding, QPSK modulation, soft-decision Viterbi receiver. Program is correct.

This code performs wide band Cooperative Spectrum Sensing under various noise levels. A large number of primary users as well as secondary users are considered.The detection is power spectral density based . This project gives the lower bound for the

本程序通过TC35模块，可以进行短信群发，主要亮点是带有短信回执判断，用于大型企业管理。(Through TC35 module, the program can send out the text message group, the main bright spot is the text message echo judgment, for large enterprise management.)
