摘要

从美国联邦通信委员会(FCC)决定在2006年完成SDTV向数字电视的过渡期开始，将对电视广播和消费电子行业产生世界性的影响。数字电视时代的到来似乎比人们预期的要早。如何面对新时代的挑战，是当前行业关注的问题。VSB传输系统在美国被接受用于数字电视的地面广播。与之对应，COFDM系统被DVB所接受。研究这两种传输方案并比较其性能和实现方法是很自然的。给出了它们性能的仿真结果，并对硬件实现进行了比较。

A comparison on VSB and COFDM used in HDTV terrestrial broadcasting

There is a worldwide impact to the TV broadcasting and consumer electronics industries starting from the decision of the FCC, of which the transition period of SDTV to digital will be completed in the year of 2006. The digital television era seems to be arriving earlier than that has ever been expected. How to face the challenge of this new era is a serious concern of the industries at present. The VSB transmission system is accepted for terrestrial broadcasting of DTV in the US. As a counterpart, the COFDM system is accepted for DVB. It is natural of interested to investigate these two transmission schemes and compare the performance and the methods of implementation. The simulation results of their performance are presented and a comparison of the hardware implementations is included.
