Coverage and capacity are the key parameters of 4G and beyond wireless networks. These parameters of Long Term Evolution Advanced (LTE-A) networks can be greatly enhanced by enabling device-to-device (D2D) communication. In this paper. full duplex amplify and forward (FDAF) relay nodes (RNs) have been introduced to assisting cellular and D2D communications. https://pipingrockers.shop/product-category/eucalyptus/
