Abstract EN
As the ever-increasing attention to green communication, energy efficiency has become an imperative metric in the emerging massive multiple-input multiple-output (MIMO) systems.
In order to maximize the energy efficiency, transmit antenna selection has been widely concerned by researchers.
In this paper, we investigate the coded cooperation transmission for dynamic transmit antennas aided two-hop massive MIMO systems.
Explicitly, we propose a rate-less codes aided cooperation scheme for reducing the implementation complexity in the broadcast phase, compared to the fixed-rate coded cooperation scheme.
Furthermore, we develop a partial cooperation scheme in the cooperative phase in order to avoid the low achievable rate caused by the full cooperation, especially when the source-to-relay (S-R) channels are poor.
Finally, the number of transmit antennas at the base station (BS) is optimized through theoretical analysis in a metric of maximizing the energy efficiency.
Moreover, we also analyze the achievable error performance for different modulations.
Our simulation results demonstrate the effectiveness of the proposed scheme.
