Abstract EN
Typical radio frequency (RF) digital beamformers can be highly complex.
In addition to a suitable antenna array, they require numerous receiver chains, demodulators, data converter arrays, and digital signal processors.
To recover and reconstruct the received signal, synchronization is required since the analog-to-digital converters (ADCs), digital-to-analog converters (DACs), field programmable gate arrays (FPGAs), and local oscillators are all clocked at different frequencies.
In this article, we present a clock synchronization topology for a multichannel on-site coding receiver (OSCR) using the FPGA as a master clock to drive all RF blocks.
This approach reduces synchronization errors by a factor of 8, when compared to conventional digital beamformer.
