Рассматриваются общие характеристики систем связи с шумоподобными сигналами, передача и прием дискретных и непрерывных сообщений. Излагаются вопросы применения корректирующих кодов, помехоустойчивости приема при различных мощных помехах, формирования и обработки таких сигналов, последние достижения в теории и практике систем связи с шумоподобными сигналами. Для инженерно-технических работников, занимающихся проектированием систем передачи информации.
