Comparison between Two Time Synchronization and Data Alignment Methods for Multi-Channel Wearable Biosensor Systems Using BLE Protocol.

近年来，无线可穿戴传感器系统在生物医学信号采集中快速发展，常部署多个传感器监测脑电图（EEG）、心电图（ECG）和肌电图（EMG）等生物电信号。与 ZigBee 和低功耗 Wi-Fi 相比，蓝牙低功耗（BLE）更适合此类系统，但现有 BLE 多通道时间同步方法（基于 BLE 信标或额外硬件）难以同时满足高吞吐、低延迟、跨商用设备可迁...
