초록
This study presents the design and FPGA implementation of a low-power, high-throughput digital modem for Medical Implant Communication System (MICS) applications. The proposed system applies a π /4-D8PSSK modulation technique to achieve high data efficiency while maintaining low power consumption. Implemented on a Xilinx Spartan-7 FPGA, the modem achieves a data rate of 16.4 ± 0.3 Mbps, with a power consumption of 0.6 ± 0.02 W/h, demonstrating a 40% improvement in energy efficiency compared to conventional 4FSK systems. The system satisfies IEEE 802.15.6 and ITU-R RS.1346 standards, with verified waveforms through MATLAB–Simulink and Chipscope. This work contributes to localization of medical implant communication technologies and provides a foundation for ASIC-based integration for next-generation biomedical and industrial wireless systems.
