The High-speed Radio Station Modem Design Based On OFDM

The radio is a commonly used in modern warfare command tools, a variety of operational information for the carrier transmission of voice, character, and data to radio waves. General-purpose high-speed data radio for the tactical Internet backbone network and high-speed wireless subnets, and can also be used for point-to-point transmission, support a variety of operating modes, and has a strong anti-jamming and self-organization, self-recovery networking capability, can important military significance and application background, so the study of high-speed data radio transmission of information at a higher rate in the battlefield under mobile conditions. Modem as the core component of the radio, the performance of the merits of a direct bearing on the performance of the radio. This paper designed to study high-speed radio modem based on OFDM technology.The dosquisition describes the status quo and development trend of similar stations first. Then, in the basic principles of OFDM, on the basis of key technologies, synchronization, channel estimation, the average peak power than OFDM system impact theory, and discussed several classic OFDM algorithm.A high-speed radio applications and environmental design, strong anti-multipath capability modem, and its performance is verified by simulation.
