there has been an upsurge of interest in full-duplex(FD) system with simultaneous wireless information and power transfer(SWIPT).Differing from the existing work
this paper optimizes the sum rates(SR) of multi-antenna FD-SWIPT system and considers its robustness and energy efficiency
also
this paper proposes robust precoding design and energy-efficient timeslot allocation scheme for FD-SWIPT system.On account of numerous variables
this optimization problem is of non-convex and hence difficult to solve.Firstly
in order to reduce the influence of self-interference
the self-interference is cancelled based on singular value decomposition(SVD) and mean-square-error(MSE) algorithm.Then
with the fixed timeslot allocation factor
on condition that there is evaluated error for self-interference channel
we propose the robust precoding design for the original problem based on first-order Taylor's series approximation
and the corresponding iterative algorithm is given.Furthermore
the timeslot allocation schemes under different constraints are proposed
and the optimal solution of timeslot allocation Factors is deduced.Finally
the performance advantages of the proposed scheme are verified by comparing the simulation experiment with the existing results.
