Claims (8)
1. Способ передачи данных на токе несущей с использованием полосы частот, который включает в себя следующие операции: разбиение указанной полосы частот на N подполос, где N целое число, равное двум или большее двух; использование OFDM (ортогонального мультиплексирования деления частоты) на каждой из указанных подполос, причем указанные подполосы активизируются и назначаются динамическим образом; осуществление операций вычисления на каждой из подполос; отличающийся тем, что вычисления, произведенные на каждой из подполос, не зависят от вычислений, произведенных на других подполосах, причем способ предусматривает использование комплекта фильтров, позволяющего произвести разбиение указанной полосы частот на N подполос.
2. Способ передачи данных на токе несущей по п.1, отличающийся тем, что фильтры указанного комплекта имеют фильтрованные подполосы с перекрытием.
3. Способ передачи данных на токе несущей по п.2, отличающийся тем, что не используют частоты, которые имеются в указанных перекрытиях.
4. Способ передачи данных на токе несущей по п.1, отличающийся тем, что число N подполос равно 7.
5. Способ передачи данных на токе несущей по одному из пп.1-4, отличающийся тем, что символы OFDM имеют размер, равный 256 несущим.
6. Способ передачи данных на токе несущей по одному из пп.1-4, отличающийся тем, что подполосы активизируются и назначаются динамическим образом при помощи программного средства.
7. Способ передачи данных на токе несущей по одному из пп.1-4, отличающийся тем, что подполосы активизируются и назначаются динамическим образом при помощи аппаратного средства.
8. Устройство для модуляции и демодуляции, предназначенное для осуществления способа по одному из пп.1-7, которое содержит средства фильтрации, средства вычисления БПФ (быстрого преобразования Фурье), средства аналого-цифрового преобразования, средства усиления и средства активизации и назначения подполос.
