A modified digital to digital encoding method to improve the Wireless Body Area Network (WBAN) transmission

Online healthcare plays an important role in the information and communication age. Wireless Body Area Network (WBAN) is one of the utilized networks in healthcare. Secure and accurate data transmission is very important in WBAN. This paper presents a new digital to digital encoding by improving None Return to Zero-Inverse (NRZ-I) digital to digital encoding. The proposed digital to digital encoding, which is called Modified NRZ-I (MNRZ-I), has great improvement in synchronization between transceiver. The results show that the propose method has considerably improvement in the direct current component, the number of invalid bits and bandwidth in comparison with other digital to digital encoding method.
