FPGA Implementation of RF Based Wearable device of Body Channel Communication (BCC) with RZ Uni-polar Encoding and Decoding using D-QPSK

摘要

In the present world, the developments of new ideas and growth of inventions are at very high rate, especially in the case of biomedical applications. It is the need of the hour to find out the root cause of the diseases, to alert the patients and to solve those problems by the medical practitioners. By the usage of human body wearable devices and through the Body Channel Communication (BCC), many diseases for example heart diseases, cancer and blood sugar etc., shall be easily identified and solved. This type of BCC application is helpful for sending and receiving the data vide a long range for the purpose of monitoring patients and giving treatment to them by doctors at the instant point of time during communication. In the existing BCC and associated wearable devices based systems, the human body skin is used as a communication channel for transmitting and receiving the information. In this existing mode of operation, the data transfer speed is very slow, the human freedoms are gets affected, jitter noise is get developed and the data transfer accuracy is low. In order to overcome the above problems, the proposed method is designed with DQPSK modulation using RZ-UNI Polar method. By adopting this technique in wearable devices based BCC, it is possible to realize high data transfer speed even in less bandwidth, high power efficiency and to reduce errors significantly. This proposed work is designed in VHDL Language and it is synthesized using MAX10 Altera Quartus FPGA. The results through the BER Testing and the outputs such as power consumption, chip area and data transfer delay are compared with the previous studies and tabulated.
