This paper presents a new method applied to photoplethysmography (PPG) signal with compression technique that is effectively applied to wearable devices. This data compression technique is especially effective for applications mainly focused on the user's heart rate. We applied this compression technique to PPG signals with sampling frequencies of 125 Hz (BIDMC Physionet). This method has the highest compression ratio (CR) as 77.8. Besides, the new method applies effectively to heart rate estimation without requiring complicated calculations. The proposed method can be applied to real-time system with PPG signal measurement with low-speed microcontroller unit (MCU).
