摘要
介绍了数字电视地面传输(DTTB)标准中抗多径的方法以及ADTB-T系统在抗多径技术上的改进,通过截止率计算公式,仿真并比较了各系统的抗多径衰落的性能。
This paper introduces the methods of dealing with multi-path in DTTB systems （ATSC, DVB and ISDB） and technology progress of ADTB-T. The cutoff rate expressions are derived and then the performances of different DTTB systems under AWGN channel and multi-path channel conditions are compared with computer simulations.
