JunYang JunYang, Ga Zhao, Dong Yin, Weiping Zhang · 2011
OFDM (Orthogonal Frequency Division Multiplexing) is a hot research in high-speed wireless communication field. OFDM modulation put the serial data flow into several parallel data flow, transmission on the orthogonal sub-carrier, has advantages as following: Resist multi-path fading, high spectrum efficiency, suitable for high speed data transmission and so on. It is wildly used on asymmetric digital subscriber loop, ETSI standards audio broadcast, digital video broadcast, High-definition digital TV, wireless LAN fields and so on. This paper introduces the OFDM theory, and implementation the OFDM transmission system based on the FPGA technology.
