MTech Projects List — Software-Defined Radio (SDR) 2026

Software-Defined Radio moves signal processing from fixed hardware into software. A typical SDR chain has three core parts:

1. RF Front-End

Captures or emits physical radio frequency signals via an antenna and handles basic amplification or tuning (LNA, mixer, filters, LO).

2. Data Converters

Uses an Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC) to convert signals into the digital domain as early as possible.

3. Digital Processing

Employs general-purpose processors, FPGAs, or specialized system-on-modules to run waveform software (demodulation, decoding, protocol stacks).
