| Main Objective: In this project we will consider the design and implementation of energy efficient wireless sensor networks with physical layer security (PLS), based on multi-antenna transmitters using low-complexity, power-efficient nonlinear amplifiers. The basic approach is to decompose at each sensor the variable-envelope signals as the sum of several components with constant or quasi-constant envelope. The transmitter is designed to have multiple nonlinear (NL) amplifiers, each one associated to one of these signals components, where the output of each amplifier is sent to a separate antenna and the signals are combined in the channel, avoiding combination losses. Besides the energy efficiency assured by this structure due to the use of efficient NL amplifiers, physical security is also achieved due to the constellation shaping associated with the use of the antenna array. |
