Information technology of OFDM-FHSS system construction based on optimal time-frequency sequences and Reed-Solomon codes was designed in the paper. The usage of developed information technology in practice will improve noise immunity and reduce the complexity of radio communications used OFDM-FHSS technology.

Adaptivní OFDM

Cílem této práce je prostudovat možnosti adaptivního nastavení systému OFDM. Studie řeší způsob získání potřebných informací o jednotlivých frekvenčních subkanálech pomocí pilotních signálů a využití těchto informací k nastavení systému. Práce představuje princip water-fillingu pro přidělování výkonu subkanálům na základě jejich SNR a mechanismy ...
