Implementation of Time Reversal Technique for Energy Efficient Wireless Communication

Priyanka, P P (2015) Implementation of Time Reversal Technique for Energy Efficient Wireless Communication. MTech thesis.



From the past few years, the mobile industry has developed quickly, providing network coverage to more than 4 billion users. So more network infrastructure and maintenance of network is required which increases the energy cost and energy consumption.. So “Green” wireless communication is taking much effort for improving energy efficiency and to reduce environment impact. A new energy efficient Time Reversal Technique is proposed. Time reversal is a pre-filtering/focusing signal processing technique for green wireless communication. The temporal effect and spatial focusing effects reduce the interference and receiver complexity for TR wireless communication. In multi path environment it adds all the reflected signals constructively and increase the signal strength at the receiver. It require low transmit power than the direct transmission of signal. Therefore the focusing property of TR simplify receiver design. The theoretical and simulation analysis show reduction in transmit power and improved BER. In this thesis work, time reversal technique and its focusing properties are studied in detail. The temporal and spatial focusing effects of TR technique are simulated in MATLAB. TR technique is implemented for single user and multi user case. A new wireless channel access method Time Reversal Division Multiple Access also implemented for multi user downlink link system.
