早在七十年代,人们开始研究无线电通信技术。无线电通信技术有线电通信相比,具有不用架设传输线路线、脱离传输距离限制、传输距离远、通信灵活等优点,备受市场的青睐。无线电通信技术为人们的生产和生活带来的影响无疑是巨大的,但它亦有不容忽视的缺点,譬如声音、文字、数据、图像和视频等传输的质量不甚稳定,由此造成的声音失真、文字模糊、数据滞后、图像和视频失真都亟须改进之处,还有信号容易受到干扰、容易被人截获造成通信内容保密性差[1],尤其在军事和经济领域,再一次说明无线电通信技术通信方法的拓新势在必行。本文就无线电的优缺点进行分析,探讨其通信技术所需拓新之处,并提出建议。
As early as the 1970s, people began to study radio communications technology. Compared with the wired and wireless telecommunication technology, it has been favored by the market because it has the advantages of not having to set up a transmission line line, separating from a transmission distance limit, transmitting a long distance, and having flexible communications. The impact of radiocommunication technologies on people’s livelihood is undoubtedly enormous, but it also has its own shortcomings that can not be ignored, such as the unstable quality of voice, text, data, images and video transmissions, and the resulting sound Distortion, blurring of the text, lag in data, distortion of images and video are all areas in need of improvement, and signals are easily interfered and easily intercepted resulting in poor confidentiality of communications [1], especially in the military and economic fields, The expansion of communication technology communication method is imperative. In this paper, the advantages and disadvantages of radio analysis, to explore the communication technology needed to develop new areas, and make recommendations.
