Turbo码在数字地面电视广播系统中的仿真研究

Turbo码以其优异的纠错性能被应用到许多领域,尝试把先进的Turbo码技术引入到数字地面电视广播系统的信道编码方案中,并利用仿真系统针对译码算法、交织器技术、通信信道等不同的系统参数对改进后的系统的性能影响进行仿真研究。仿真结果表明,引入Turbo码的系统性能优于原DVB-T系统。

Research and Simulation of Turbo in DVB - T System

Turbo code is applied to many fields by reason of excellent performance of correcting.In this article,Turbo code technology is inserted into the channel coding scheme of DVB-T.The performance is investigated between standard DVB-T and improved DVB-T with different parameters of decoding algorithms,interleavers,communication channels through simulation.The simulation result shows that the error-correcting performance of improved DVB-T is better than standard DVB-T.
