Simulation of 802.11B at the Physical Layer with DBPSK Modulation

This simulation experiment focuses on implementing 802.11B protocol at the physical layer using DBPSK modulation. The simulation models the complete transmission process including signal modulation/demodulation and channel transmission characteristics. Through MATLAB or similar simulation platforms, we can implement key components such as: - DBPSK modulator using phase difference encoding between consecutive symbols - AWGN channel model with configurable signal-to-noise ratio (SNR) parameters - Correlation-based demodulator with differential decoding logic - Bit Error Rate (BER) calculation and performance analysis These simulations enable comprehensive understanding of 802.11B wireless network performance characteristics, including robustness to noise and transmission efficiency under various channel conditions. The implementation typically involves creating baseband signal processing chains and analyzing constellation diagrams for modulation quality assessment.
