FPGA Implementation of a Wideband Multi-Gb/s 5G BF-OFDM Transceiver. In: 2021 Joint European Conference on Networks and Communications 6G Summit (EuCNC/6G Summit), pp. 502–507, IEEE, 2021.
Abstract
This paper describes a Field Programmable Gate Array (FPGA) implementation of a multi-Gb/s Block Filtered (BF) OFDM transceiver, fully 5G NR compatible. The main obstacles for such a work are (i) the support of multiple configurations and parameters, (ii) the high bandwidth w.r.t the board clock frequency and (iii) the intrinsic complexity of BF-OFDM. We prove that despite these barriers an hardware implementation of this waveform is possible, even with a bandwidth up to 400 MHz. We based our developments on the following pillars: smart layout of the basic modules, parallelization of dedicated functions design and ad hoc architecture. Measurements and complexity analysis demonstrate the high flexibility of BF-OFDM.
