1 excess bandwidth
избыточная ширина полосы частот
Ширина полосы частот, значение которой превышает минимально необходимую для передачи, определяемую по критерию Найквиста, т.е. Fиз>½Т, где Т - длительность символа. Расширение полосы частот является одним из эффективных методов снижения межсимвольных искажений.
