Abstract
Предлагаемый способ передачи данных между терминалом и переносным носителем информации по линии беспроводной связи, с помощью электромагнитной энергии, заключается в том, что сигнал несущей частоты, модулированный передаваемыми данными с помощью амплитудной манипуляции, при значении коэффициента модуляции 100 %, используется в переносном носителе информации в качестве сигнала синхронизации, а значимость разряда данных зависит от положения момента изменения амплитуды сигнала несущей частоты в пределах временного интервала, выделенного для передачи данных. Длина слова данных составляет N битов (N ( 2). Для передачи указанного слова данных используются 2N изменений амплитуды сигнала несущей частоты в пределах указанного временного интервала. Временному интервалу, выделенному для передачи данных, предшествует нулевой временной интервал, в течение которого передача данных отсутствует, чтобы исключить передачу ошибочных данных в результате неприемлемого увеличения периода двумя моментами изменения амплитуды сигнала несущей частоты.
