Error Rate Analysis of MDPSK Modulation in Biological Channel

摘要

Implantable and wearable medical devices provide convenience for patients through wireless communication. However, due to the complexity of the channel, the error rate characteristics need to be paid special attention. Based on the empirical formula of MDPSK modulation error rate in AWGN channel, the error rate model was optimized combined with biological channel path loss of implantable devices and body surface multi-path effect in wearable devices. The models build in this paper have more practical guiding significance.
