Особенности моделирования одночастотных сетей цифрового телерадиовещания стандарта DVB-T

Особенности моделирования одночастотных сетей цифрового телерадиовещания стандарта DVB-T

Abstract

The problems of simulation and analysis of the single frequency digital television broadcasting nets under the DVB-T standard are discussed. The main point of investigation is the allowance for signal spreading in the mutibeam re-reflection environment. The simulation results are used in calculation of the coverage areas of digital television broadcasting.

Рассматриваются вопросы моделирования и исследования одночастотных сетей цифрового эфирного телерадиовещания стандарта DVB-T. Основное внимание уделено учету особенностей распространения радиосигналов в условиях многолучевого переотражения. Результаты моделирования используются при расчете зон охвата телерадиовещания при переходе на цифровой формат.
