Abstract :
This paper analyzes the spectral efficiency of the distributed multi-input multi-output (D-MIMO) system with antenna cooperation over the rayleigh-log-normal fading channel. Under the cooperative transmission scheme (CTS), analytical expressions of the ergodic normalized capacity and outage capacity are derived. Moreover, to optimize the system performance, an adaptive CTS (ACTS) is proposed by the criterion of minimizing the outage capacity, and a theoretical expression is derived to operate the ACTS. Simulation results are presented to verify the theoretical outcomes.
