Chronic patients have to been monitored continuously for reducing the risk in patient’s life. Recent years, healthcare equipments uses the communication modules for Tele monitoring applications. Preestablished power distribution system has drawn the attention of many researchers for communication applications. In this paper, we present the application of Power Line (PL) as a communication channel for transferring the biosignals. Transducers are placed at the appropriate locations for acquiring the biosignals, which are transmitted and received using the low voltage single phase power lines. Personal Computer (PC) interfaced with the receiver unit will be displaying the decoded signals. In MATLAB, orthogonal frequency division multiplexing (OFDM) is used for transmitting the data over the simulated power line channel (SPLC) and its performance is evaluated based on Bit Error Rate (BER). From the experimental results, it was observed that EEG and ECG signals were deformed due to the PL noise and disturbances. From the simulation results, the BER can be reduced by increasing the Fast Fourier Transform (FFT) size and by varying guard time size. It can be concluded that, power lines will be an cost effective way for communication with considerable speed and accuracy.
