摘要
设计一种用于HDTV地面数字传输系统的级连格状编码和RS码方案,并对其在HDTV中应用进行计算机模拟。模拟结果表明:该级连格状编码方案在低信噪比具有较好的误码性能。
This paper designs the scheme that is used for digital HDTV terrestrial transmission, consisting of a trellis code and a Reed -Solomon code. We simulate the scheme with computer. The simulation result indicates that the scheme has a good error performance in low signal -to-noise ratio.
