GFSK modulation for BLE baseband IC design

Bluetooth low energy (BLE) is widely used for short distance and low rate communication. GFSK modulation is also widely used, because of its excellent power utilization and spectrum utilization. Compared to GFSK analog modulation, digital GFSK modulation is lower in the bit error rate. In this paper, the digital GFSK modulation is studied, and the GFSK modulation scheme is proposed and simulated by MATLAB, which is suitable for Low Power Bluetooth baseband chip.
