Saksham Dewan

I study how machine learning can shape the signals we transmit and the receivers that recover them.

My research connects wireless and optical communications with learning—working toward reliable systems under channel impairments, hardware limits, and constrained computation.

Research

What can we gain by learning the waveform and receiver together? I explore this question across radio-frequency and optical systems, with particular attention to robustness and receiver complexity.

More resilient signals.
Lower power peaks.

Jointly learning transmit and receive bases to reduce interference from residual carrier-frequency offset, alongside a model-guided receiver that refines symbol estimates.

The work explores the tradeoff between communication reliability and peak-to-average power ratio.

Giving optical signals
more room to adapt.

Learning constellation geometry and receiver decisions together under LED clipping constraints, including modulation orders beyond the usual powers of two.

This allows finer control of transmission rate in visible light communication systems.

04Master’s research

Shared learning.
Efficient receivers.

Using cross-stitch neural networks to recover multiple information streams within a composite VLC waveform, sharing useful features between related demodulation tasks.

An interpretable measure of task dependence helps explain when that shared processing is useful.
