This paper investigates an integrated wireless communication system including non-orthogonal multiple access, fullduplex relaying, and energy harvesting techniques (named as EH-FD-NOMA). In this scheme, an energy-limited full-duplex relay harvests energy from a source at the first stage. Then, the relay detects the superimposed signal from the source and transmits the decoded signal to destination. Closed-form outage probabilities and ergodic rates at the relay and destination are derived. Numerical results verify the analytical results and show the superior performance of the EH-FD-NOMA if compared to its counterparts.

The genetic algorithm is briefly introduced and its complete programming is provided in detail by MATLAB7.0. In addition, the application in optimization of functions and solution of equation is shown through three examples and the method of avoiding local optimization by increasing the value of pm is also discussed.
