Title: THE CORDIC ALGORITHM
Abstract:
The CORDIC (Coordinate Rotation Digital Computer), originally proposed by a mathematician named Volder in 1957, is an iterative algorithm to compute trigonometric quantities. In seventies, with the advent of FFTs, this found a ready usage in the hardware implementation of the twiddle factor based multiplications in the FFT. Subsequently, it found application in many other areas of signal processing and by eighties, it was recognized as an elegant tool for a wide array of signal processing jobs like FFT, DCT, Walsh-Hadamard transform etc., matrix operations like QR factorization, SVD, eigen-analysis etc. and also for multiplierless realization of digital filters. This seminar will present the CORDIC algorithm by developing it from basics and would consider its hardware implementation in terms of the so-called pipelined CORDIC units. It will conclude by showing some elegant applications of CORDIC.

Title: Deep Learning in Wireless
Abstract
The ability of deep learning to extract feature and perform pattern recognition accurately from complex raw data makes it a potential candidate for design of wireless networks with large-scale topology and complex channel conditions. The wireless communication dynamics involving channel interference, traffic congestion, spectrum availability can be analyzed based on large amount based obtained from network parameters like delay, signal-to-noise ratio, throughput, probability of error etc. The talk delves on how deep learning can equip the wireless network with capability to handle and accept a large number of parameters, such as SNRs, channel holding time, collision rates, routing delay, packet loss rate, bit error rate, etc., and determine intrinsic patterns like congestion degree and occurrence pattern, interference alignment, hotspot distributions, etc. Such patterns can be used to perform the protocol controls at different layers. The talk also discusses some unsolved research issues in deep learning wireless networking like end to end congestion control, cross layer design, cognitive radio including effect implementation of distributed deep learning on wireless nodes that may have long-term dominant impacts

Title:Towards Connected Robots
Abstract:
While the current and near-future focus of ICT systems is on automating pure IT related tasks, we have started exploring automating physical tasks (like mobile surveillance, sorting of items etc) via Robots for future smart enterprises/cities. One of them key research challenge is related to programming and control of network of robots to work in unstructured environments. Technologies like 5G, Infrastructure Assists and experiential learning will become key to enable such technologies. We will describe our current attempts and future plans at data driven, connected robotics.

Title: Ultra wideband Radar systems: Concepts & Applications
Abstract:
Conventional radars used primarily for surveillance, tracking and fire control have resolution in the order of km to few meters used mainly for Ariel targets (air craft) detection. The advent of new asymmetric threat to the nation in recent times due to terrorism and naxalism calls for new types of sensors and radars with the range resolution up to few centimeters. Short range Radars like through wall imaging radars for better situational awareness for rescue team in hostage situations, ground penetrating radars for landmine detection and Clarence in the naxal affected areas are new requirements for homeland security. The common technical requirements for these radars is very high bandwidth for better resolution and lower operating frequency for better penetration through the barriers(Wall, soil etc).These contrary requirements of large bandwidth and lower frequency calls for use ultra-wideband technologies. Design of compact short range ultra wide band systems present new challenges and new opportunities in the field of electromagnetic and signal processing. This talk will introduce to various UWB radars applications and the concept of Time domain electromagnetic and signal processing suitable for UWB short range radars applications.

Title: Signal Processing in Mobile Communication Systems.
Abstract:
The talk will review the role and extensive use of Signal Processing techniques and methods in Mobile Communication Systems over its past five technology generations for improving Spectral Efficiency, Overcoming Channel Imperfections, Enhancing Data Rates, User Density and Mobility, Creating Voice, Data & Video Integration while reducing the cost of services and Data Rates for the consumers. The continual impact of Signal Processing has been in evolving innovative Signal Design, Coding methods for Spectral Efficiency, Data & Network Security, Channel Modelling, Adaptive Power Control & Media Integration so as to provide seamless experience to the users across the multiple level of services being offered over the mobile platforms to millions of users by multiple service providers through global standards and across the multiple Generations of Mobile Technology. The continuing explosive growth & demand of Mobile services to more and more consumers with multiple services while meeting the future expectations of IoT, UDN, Autonomous Systems, and GB Data Rates is driving the technology to create implement and deploy 5G standards for meeting existing and future needs of Mobile Services. The 5G Standards, implementation strategies, testing and PoC have been evolving over past one decade and the various suggestions for type of signals to be used, processing and implementation methods needed to meet the stringent specifications evolved by ITU – R and WP5 for IMT- 2020 are now almost tested in the labs on test benches and even in a live scenario. The commercial deployment is going to be in the coming year with few equipment manufacturers, service providers and handset manufacturers coming out with products and plans as per schedule. This is going to need trained and qualified field personnel & manpower to be available for deployment, maintenance and servicing of 5G infrastructure.
