Design and Simulation of a Matched Filter Receiver 

This project focused on designing and simulating a digital communication receiver using a matched filter to improve detection performance in noisy environments. A BPSK communication system was implemented and analyzed to demonstrate the effectiveness of matched filtering. 

Objectives

• Implement the matched filter concept for a digital communication system.

• Design a complete BPSK receiver chain.

• Compare receiver performance with and without matched filtering.

• Evaluate system performance using bit error rate (BER) analysis.

Outcomes & Contributions

• Successfully implemented a BPSK communication system over an AWGN channel.

• Demonstrated that the matched filter significantly improves BER performance compared to direct sampling.

• Identified the optimal sampling (decision) time for reliable symbol detection.

• Verified simulation results against theoretical expectations.
