Igor’s expertise focuses in the field of Digital Signal Processing (DSP) for Communications. His research and work over the past 4+ years covered topics such as signal processing for G.fast Digital Subscriber Lines, highly-parallelized DSP schemes for optical communications and clock synchronization. Such R&D efforts were conducted over several projects funded by external university partners, in which he leaded the full process of physical layer innovation, from theoretical conception, to simulation, up to prototyping using microprocessors and FPGAs.
His current research focuses on the algorithms and hardware architectures to support synchronization between remote radio units (RRUs) and baseband units (BBUs) that communicate over Ethernet fronthaul networks. The goal is demonstrate the capabilities of an Ethernet-based fronthaul to achieve the accuracy required by multi-cell and multi-user MIMO transmission schemes. He is investigating techniques that span a variety of topics, from time-sensitive network packet transmission schemes, to estimation theory, digital communications and control systems, all of which are materialized through his VHDL/C developments in an FPGA-based testbed. He is aspired to bring the next-generation of cost-efficient fronthaul solutions that will reduce the costs of denser indoor 5G deployments exploiting the widely available Ethernet cabling and equipment infrastructure.
