As a key member of the Phazr team, Dr. Sudhir Ramakrishna is expanding his knowledge base, operating out (sometimes way out!) of his comfort zone, and having a blast, all the while building the world’s first commercial gigabits-per-second mmWave cellular systems.
A brief bio and summary of his pre-Phazr life:
He has over 18 years of experience in the communication systems R & D industry. From May 1998 to June 2008, he was a Member of Technical Staff at the Network Business Unit of Lucent Technologies, Bell Labs Innovations (later Alcatel Lucent, Inc.) at Whippany, NJ. From July 2008 to August 2016, he was a Principal Engineer at Samsung Research America at Richardson, TX.
He is an expert in the overall operation of cellular and wireless communication systems, with a focus on the Physical- and MAC-layers, covering the entire gamut from modem algorithms to resource allocation algorithms. His expertise encompasses MIMO operations in conventional low frequency bands as well as mmWave band systems. While at Samsung, as a key member of the team that pioneered the usage of mmWave bands for cellular communications, he conducted research into the hybrid-beamforming aspects of mmWave systems. He has been a key member of several prototyping efforts, the latest of which was in the development of a pre-LTE Release 13, 32 antenna FD-MIMO proof-of-concept system, also at Samsung.
He is an expert in the signal propagation models for cellular and WiFi environments, as well as in the system- and link-level modelling of cellular communications systems. He has participated in several standards body channel model and simulator calibration campaigns, the latest of which was w.r.t the 3GPP NR mmWave channel model calibration campaign while he was at Samsung.
He has extensive experience in developing system-level simulations in the C, C++, and MATLAB environments, and conducting performance studies into resource allocation algorithms, deployment options, areal capacity, coverage, and business use-cases. He has developed system-level simulators w.r.t the 3GPP2 EV-DV, IEEE 802.16-M (M-WiMAX) and 3GPP LTE specifications.
He has participated in the standardization of communications systems operation specifications as a delegate to various standards bodies. While at Lucent Technologies, he supported, and was a delegate to, the 3GPP2 standards body. While at Samsung, he was a delegate to the IEEE 802.16-M (M-WiMAX) standards body, where he led the development of key portions of the resource allocation signaling specifications. He has extensive knowledge of the 3GPP LTE specifications.
He is a team player with excellent communications, leadership, and team-building skills. Over the course of his career, he has been a lead in several projects, interacting with locally- and overseas-based team members. Participation in standards body activities have given him the opportunity to interact with peers from organizations all over the world, honing his negotiation and communication skills.
He received his B-Tech degree from the Indian Institute of Technology at Mumbai, India, in 1992, and his MS & PhD degrees from Rutgers University, New Brunswick, NJ in 1998. His PhD research was conducted at the Wireless & Networking Lab (WINLAB) of Rutgers University. All his degrees are in Electrical Engineering.
