This paper investigates performance of a mixed radio frequency (RF)/free space optical (FSO) two-way relaying system. A half-duplex two-way relay is adopted to establish the communication between both RF and FSO links. Under this scenario, the associated end-to-end statistical features of the system are derived. They are then used for calculating outage and average symbol error rate (ASER) of M-ary...
We consider a multi-pair massive multiple-input multiple-output (MIMO) two-way relay network, where multiple pairs of single-antenna users exchange data with the help of a multi-antenna relay station. We assume that the relay is equipped with a large antenna array, but driven by a far smaller number of RF chains, which can enormously reduce the hardware cost and complexity for practical applications...
This paper investigates the average symbol error rate (ASER) performance of a dual-hop hybrid relaying system relying on both radio frequency (RF) and free-space optical (FSO) links. Specifically, an RF link is used for supporting mobile communication, whereas an FSO link is adopted as the backhaul of the cellular infrastructure. Considering nonline-of-sight RF transmissions and a generalized atmospheric...
