In this paper, we propose and analyze a new relaying scheme for the three-node
cooperative relaying system, named as incremental hybrid decode-amplify-forward relaying …

With a great potential to support multitudinous services and applications, mobile device-to-
device (D2D) communications are conceived as a candidate paradigm for the future …

Two-tier femtocell networks are an efficient communication architecture that significantly
improves throughput in indoor environments with low power consumption. Traditionally, a …

A relay cooperation scheme is proposed for the downlink of multicell multiple-input-multiple-
output cellular networks. The relay stations (RSs) will cooperatively transmit the signal …
