Hi, I'm Aakarsh Dhariwal

Wireless Systems & Signal Processing engineer working across RF communications, underwater acoustics, and DSP algorithm design — from MATLAB/Python simulation through hardware-validated prototypes.

Currently

Project Research Engineer, IIT Delhi (CARE) — designing and validating a full-stack underwater acoustic communication system in MATLAB, integrated with SONAR transducers and a DAQ unit for water-tank trials, recovering 92–95% of transmitted data through a heavily distorted acoustic channel.

Background

  • MSc Communications & Multimedia Engineering, Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany) — wireless communications, signal processing, 5G.
  • B.Tech Electronics & Electrical Engineering, Vellore Institute of Technology (VIT), India.
  • Previously: DSP working student at WS Audiology (Erlangen), IRS codebook design research internship, BLE scanner app for wireless environmental sensing (IIT Ropar AWaDH Fellowship).

Research

Project What it does
irs-codebook-design Near-field codebook design for Intelligent Reflecting Surfaces, extending a far-field linear phase-shift codebook and evaluating it under discrete PIN-diode phase quantization, phase error, and phase noise. Research internship, FAU Institute for Digital Communications.
rss-localization-5g-spectrum-sensing RSS-based transmitter localization (MSE & LIvE methods) and radio environment map reconstruction via distributed spectrum sensing, extended to a 5G-NR-style OFDM waveform. Master's thesis, FAU Chair of Electrical Smart City Systems — localizes the transmitter to under 1 m with 9+ sensors.
image-video-compression-lab From-scratch hybrid video codec — block DCT, quantization, motion estimation/compensation, Huffman coding — extended with half-pel motion estimation, rate-distortion-optimized coding decisions, and in-loop deblocking. Beats a JPEG baseline by 39.9% BD-rate. FAU Image and Video Compression Lab Course.

Featured projects

Project What it does
blind-pulsed-emitter-detection Detects, separates, and characterizes multiple pulsed radar emitters — carrier frequency, direction of arrival, PRI — from raw multi-channel IQ captures, with no prior knowledge of emitter count or timing.
Autoencoder-for-Signal-Processing-and-Data-Compression PCA vs. autoencoder compression for IQ data streams, built at a Rohde & Schwarz-hosted hackathon (16:1 compression ratio, −18.55 dB EVM).
RADAR-Project SISO OFDM radar processing chain recovering range and velocity of moving targets via subcarrier-domain matrix operations.
