About Amitkumar Mahadevan, Ph.D.

As a systems, algorithms, and firmware innovator, I take pride and satisfaction in delivering quality signal processing solutions for the telecommunications industry. My expertise spans a significant swath of the SoC product development spectrum; this includes (a) conceiving novel ideas and algorithms, (b) vetting proposals for feasibility via theoretical analysis, modeling, and simulations, (c) designing digital systems with an eye on hardware / software partitioning, (d) verifying / validating the design, (f) developing finite precision algorithms and firmware for embedded systems, (g) debugging anomalous behavior during system operation, and(h) advocating technologies and demonstrating product capabilities via live customer demos.A creative thinker and a co-inventor on more than 25 issued patents (see http://patents.justia.com/inventor/amitkumar-mahadevan), my greatest strength is the ability to solve complex problems by leveraging my broad knowledge base in conjunction with the wherewithal to dive into minute details.I am a versatile collaborator with experience in working with and managing geographically distributed teams to deliver robust solutions under tight time-constraints.I am a believer in leading by example and I relish opportunities to share my know-how through training and mentoring.Key technical areas of expertise:• OFDM / DMT systems• Source & Channel Coding, FEC, LDPC Codes• Vectoring, Crosstalk Cancellation, MIMO • DSP, Adaptive Algorithms• Simulations & Modeling (Matlab, Algorithmic C, C++)• Firmware Programming for Multiprocessor & Multithreaded Embedded Systems (C, Assembly)• Finite Precision Signal Chain Design • Hardware / Software Co-Verification (Cadence Palladium)You can reach me directly at amitkumar.mahadevan@gmail.com
