Relays are used in the current wireless standards to enhance the cell throughput and coverage. In this paper, we evaluate the system performance by considering the duplexing loss with over-the-air transmission for relay with decode-and-forward as the relaying protocol. The overhead involved in providing the relay with the data prior to the transmission is often neglected. We demonstrate that the impact...
Space-frequency resource allocation and multiuser beamforming are crucial techniques to obtain high spectral efficiency requirements of IMT-A technologies. In this paper, we consider system level evaluation results of downlink TDD based LTE-A MIMO-OFDMA networks in ITU-R specific IMT-A evaluation environments. Efficient multiuser MIMO beamforming with and without intra-site coordinated multipoint...
