Digital Meter Reading through Power Line

This report deals with the communication through power line, its various aspects and the transmission through power line. This project deals with the transmission device, the receiver device and interfacing the devices to microcontroller and the computer. Brief description of the different sections is also given.

The transmission device used is the FSK transmitter which is operated at two centre frequencies and the non-coherent demodulation is done at the FSK receiver.

This project also deals with the programming the microcontroller that demodulates the Hamming Code used for the error detection and correction. Since this project deals with the introductory phase for layers, the microcontroller is programmed for the data link layer that can correct one bit error. Various layers that can be used for communicating through the power line are also described.

C program for the computer for application of different physical layers is also included.
