摘要
研究了数字电视微波传输技术,根据各项数字化改造指标,使改造后的微波传输系统达到设计要求,可将误码率控制在≤10-6,信号电平储备为>20 d B,保证了电视广播传输在图像质量方面的稳定性。采用数字信号传输,有效的消除了原有模拟传输所带来的诸多问题,同时还保留了微波自身的优势,如抗击自然灾害能力强和易维护等特点。
Abstract This paper analyzes the use of microwave transmission for digital TV. By indicators for the digital transformation plan, the transformed microwave transmission system can have the BER ≤ 10 ^-6 and the digital signal level reserve 〉 20 riB, which guarantees the stability of the image quality and broadcast transmission. Digital microwave transmission of digital television signals effectively eliminates the problems in analog transmission and also has the advantage inherent in microwave of strong resistance to natural disasters and easy maintenance.
