Wireless Powered Communication Networks: TDD or FDD?. (arXiv:1807.05670v1 [cs.IT])
来源于:arXiv
In this paper, we compare two common modes of duplexing in wireless powered
communication networks (WPCN); namely TDD and FDD. So far, TDD has been the
most widely used duplexing technique due to its simplicity. Yet, TDD does not
allow the energy transmitter to function continuously, which means to deliver
the same amount of energy as that in FDD, the transmitter has to have a higher
maximum transmit power. On the other hand, when regulations for power spectral
density limits are not restrictive, using FDD may lead to higher throughput
than that of TDD by allocating less bandwidth to energy and therefore leaving
more bandwidth for data. Hence, the best duplexing technique to choose for a
specific problem needs careful examination and evaluation. 查看全文>>
