1.0 English

Synchronization requirements in emerging RF applications are challenging due to the increasing number of antennas used. The majority of new radio applications use MIMO with OFDM encoding to increase the capacity of the radio links. MIMO, when coupled with direct RF conversion and digital signal processing, requires advanced processing to preserve the phase coherency in the digital RF transceiver design.
