一种改进的无线电通信系统的设计

针对传统短波通信系统的不足，设计了一种改进型的短波／超短波通信系统。该系统能够把计算机与短波／超短波电台连接起来，实现文本、图像等数据在短距离范围内的无线传输，同时利用计算机实现对通信数据的存档。实验证明，该系统抗噪声性好，误码率低，能够满足短波无线电数据通信的要求。

Design of Improved Wireless Communication System

Aiming at the shortage of traditional shortwave communication system, an improved wireless communication system in shortwave/ultra-shortwave is designed and implemented： This system could connect computer to shortwave/ultra-shortwave broadcasting station and thus accomplish the wireless data transmission of short distance. The experimentations have proved that the new communication system is fairly noise-resistant and low in error-bit rate, thus could satisfy the requirement of shortwave wireless data communication.
