What This Document Is
This document outlines a comprehensive project for the Digital Signal Processing (DSP) course (ELENG 123) at the University of California, Berkeley. It details a hands-on assignment focused on implementing a wireless digital communication system using readily available hardware – the sound card and microphone of standard laptops. The project requires students to transmit information wirelessly, specifically an image, and reconstruct it at a receiving end. It’s a practical application of DSP principles, demanding both theoretical understanding and coding proficiency.
Why This Document Matters
