Simulation Design of Bluetooth Frequency Hopping Communication System

This document describes the simulation design of a Bluetooth frequency hopping communication system. Using MATLAB's SIMULINK simulation platform, we have architecturally divided the system into seven modular components: the frequency hopping transmission section implementing channel hopping patterns, the FH-CPM modulator subsystem handling Gaussian Frequency Shift Keying (GFSK) modulation, the signal reception section with RF front-end simulation, the FH-CPM demodulator subsystem performing signal detection and decoding, the dis-assemble packet subsystem for data frame reconstruction, the spectrum analysis module for frequency domain characterization, and the bit error rate analysis module for system performance validation. The complete simulation framework is organized across six MDL files, incorporating frequency synthesizer models, hopping sequence generators, and correlator-based receivers to enable comprehensive performance evaluation of the Bluetooth frequency hopping mechanism under various channel conditions.
