Bluetooth Frequency Hopping Simulation System

Signal sequence generation and mapping onto frequency hopping channels. The system employs a Bernoulli random signal generator module to create random signals with a frame sampling rate of 10 and sampling time of 1.5e-6. Signals are preprocessed and mapped onto a 1600 hops/second frequency hopping pattern. The modulation scheme uses FH-CPM (Frequency Hopping-Continuous Phase Modulation), where the original signal undergoes CPM modulation to produce binary symbol sequences with a pulse length of 1. Simultaneously, the frequency hopping signal at 1600 hops/s is modulated using M-FSK, generating a hopping sequence ranging from -39MHz to 39MHz. These two sequences are multiplied to produce the output signal for transmission. The receiver utilizes an identical random frequency hopping sequence for demodulation, reversing the preprocessing steps through dedicated subsystems.
