The Study Of An Asymmetric Digital Access Method And Its Key Technic

A design and realization method of an asyIYUnetric digital connectiontecboque used in high-speed cable remote data transmit (HSCRDT) is present in thispaPer. Some analysis of basic specification of this system are put on. Aimed at theconfined condition in this system, several design method are presented and comPared.Also, the basic principles, system contriction and characteristics of OFDM(Owhogonal Frequency Division Multiplex) are presented, with emphasis on the symbolsynchronization, sarnple clock synchronization, equalization and bit loading. Finally thekey structure and system parameters of this system is also given.
