- Abstract
In this paper, antenna selection at transmitter in Space Shift Keying (SSK) is considered, which conveying information using the bit-determining antenna from two potential antennas. Previous researches mainly focused on information transmission, and the main performance metrics are bit error rate (BER) and capacity. Simultaneous wireless information and power transmission (SWIPT) has recently drawn significant research attention. In SWIPT systems, receiver can not only receive information but also harvest energy. Wireless energy harvesting (EH) has been proposed to prolong the operation of energy-constrained wireless networks. Combining SSK and EH together in our work, the main challenge is to find the best antenna combination. For this, we put forward an objective function to get the tradeoff between BER and EH. Exhaustive search is firstly adopted to accomplish the task, and it shows the scheme can get the best result at the cost of high complexity which may not be affordable when the transmit antenna number is large. To lower the complexity, three other criterions are proposed to work the result out rapidly with lower computation complexity while not deteriorating the BER performance much.
