Abstract

Запропоновано цифрову лінеаризовану систему для автоматичного регулювання підсилення (АРП) радіотелефонів та спосіб АРП. Прийнятий сигнал демодулюється для одержання I і Q цифрових сигналів. З цих сигналів одержується значення сили прийнятого сигналу і результуючий цифровий сигнал регулюється для одержання логарифмічного виходу. Цей сигнал потім інтегрується для одержання цифрового приймального регулюючого сигналу для АРП. Для керування передавальною системою АРП цифровий приймальний керуючий сигнал для АРП фільтрують, потім складають з каліброваною командою замкненого контура керування потужністю. Команди замкненого контура керування потужністю ігноруються, якщо вони призводять до підвищення підсилення при передачі до неприпустимого рівня. Виходи приймального і передавального підсилювачів з АРП лінеаризуються у приймальному і передавальному лінеаризаторах відповідно, де цифрові сигнали керування АРП також піддаються попередньому спотворенню перед надісланням до ЦАП.
