Description: ，用MATLAB实现快跳频通信系统的仿真。主要应用了SIMULINK和COMMUNICATION BLOCKETS两个模块。整个设计包括了信源产生部分、发送部分、跳频调制部分、信道部分、接收部分和结果分析部分共六个模块，核心技术是伪随机序列的产生和频率合成器的设计，而关键技术是收发两端的伪随机码元的同步。伪随机码的产生用S－函数编程来开发自己的SIMULINK模块。同步的实现是收发两端采用相同的扩频脉冲触发。而且在设计中每个模块都采用了模块封装技术，从而简化了框图结构-Using MATLAB to achieve fast frequency-hopping communication system simulation. The main use of SIMULINK and COMMUNICATION BLOCKETS two modules. The whole design, including part of the generated source, sending part of some frequency-hopping modulation, channel of the receiving part and the results of analysis of part of a total of six modules, the core technology is the emergence of pseudo-random sequence and frequency synthesizer design, and the key technology is the transceivers at both ends of the pseudo-random synchronization symbol. Pseudo-random code generated by S-function programming to develop their own modules SIMULINK. Synchronization is used to send and receive ends of the same spread-spectrum pulse trigger. But also in the design of each module using the module packaging technology, which simplifies the structure of the diagram

Description: cdma是在数字技术的分支——扩频通信技术上发展起来的一种崭新而成熟的无线通信技术。即将需传送的具有一定信号带宽信息数据，用一个带宽远大于信号带宽的高速伪随机码进行调制，使原数据信号的带宽被扩展，再经载波调制并发送出去。接收端使用完全相同的伪随机码，与接收的带宽信号作相关处理，把宽带信号换成原信息数据的窄带信号即解扩，以实现信息通信。-cdma wireless communication technology in a new and sophisticated digital technology branch- spread-spectrum communication technology developed. The data will be transmitted with a certain signal bandwidth information, bandwidth of the signal with a bandwidth much larger than the high-speed pseudo-random code is modulated, so that the bandwidth of the original data signal to be extended, and then via the carrier modulation and sent. Receiver use exactly the same pseudo-random code, for a correlation processing with the received bandwidth signal, the wideband signal is replaced with the original information data on narrowband signal despreading, in order to achieve information communication.
