What is Sub-carrier Allocation Scheme Based on a Single Carrier Frequency Division Multiple Access by Using a Relay Selection about?

## This article gives a scheme for the allocation of subscribers based on multiple access with a single carrier frequency division (SC-FDMA). A discrete Fourier (DFT) transform can be used for pre-coded solutions to the PAPR issue in the SC-FDMA. In a wireless signage system based on ## SC-FDMA, a multi-hop system using relays can extend communication coverage and solve the problem of the shaded area caused by the obstacle between the signages. In the conventional multi-hop system based on SC-FDMA, the communication between a source and relay does not use a communication resource efficiently. Therefore, this paper proposes a method that can usefully use a communication resource. Additionally, A multi-hop system has a significant impact on the relay selection scheme. For selecting a suitable relay, the new method for relay selection takes into account the channel between UE and the relay, and between the relay and the venue. When considering the channel between the source and the relay, the sub transporters used to communicate between the source and the relay are taken into account only. The system proposed will use the required relay selection scheme on the basis of SC-FDMA in the
