| 摘 要： | 无线数据传输是人们普遍使用的一种通信手段,基于DSP的数字调制解调技术的研究也得到人们的高度重视。根据无线数据传输的特点,将高斯滤波的技术运用于MSK调制技术,设计了一种适合无线数据传输的GMSK调制解调器,给出了实现原理、系统框图和软件控制流程图。实际测试表明,该调制解调器提高了数字移动通信的频谱利用率和通信质量,调制后的中频信号对邻道辐射小于60 dB,符合无线通信的要求,可广泛应用于无线数传设备。

| Abstract: | Wireless data transmission is a widely used communication method,the study on the technique of modulation and demodulation based on DSP is more and more valued.This article applies the Gaussion filter on MSK modulation after thinking out of characteristic of wireless data transfer,and designs a sort of GMSK modem which fits the wireless data transfer,also presents the formula,system frame and frame of soft control.According to the conclusion of test,the modem increases the spectrum utilization and communication quality,decreases about 60 dB radiation to neighbors frequency and metes with the demand of wireless communication,which is widely applicated to the device of wireless data transfer. |
