OFDM based communication system using USRP

摘要

In this study, we implemented orthogonal frequency division multiplexing (OFDM) based communication with universal serial peripheral device known USRP. We aim to study synchronization related problems of OFDM based system in real environment. The timing, phase and channel estimation are done. Their effects to the system performance are discussed. The results show that by using right tools, synchronization problem can be addressed overwhelmingly.
