Abstract EN
An optimal resource allocation strategy for MIMO relay system is considered in simultaneous wireless information and energy transfer network, where two users with multiple antennas communicate with each other assisted by an energy harvesting MIMO relay that gathers energy from the received signal by applying time switching scheme and forwards the received signal by using the harvesting energy.
It is focused on the precoder design and resource allocation strategies for the system to allocate the resources among the nodes in decode-and-forward (DF) mode.
Specifically, optimal precoder design and energy transfer strategy in MIMO relay channel are firstly proposed.
Then, we formulate the resource allocation optimization problem.
The closed-form solutions for the time and power allocation are derived.
It is revealed that the solution can flexibly allocate the resource for the MIMO relay channel to maximize the sum rate of the system.
Simulation results demonstrated that the performance of the proposed algorithm outperforms the traditional fixed method.
