Non-Orthogonal Multiple Access (NOMA) is a promising technique to increase spectral efficiency and accommodate more cellular users. The cellular users near to the base station are always connected to the network due to the strong signal strength whereas users far from the base station suffer from poor signal reception. In order to mitigate this problem, in this paper, a coordinated multi-point NOMA cellular network with multiple cell edge-users is considered. In this system model, a practical scenario in which edge-users coordinate with two base stations is considered and nearby users are connected with the respective base station. The performance metrics such as outage probability and system capacity are derived for this system model. In addition, an algorithm has been proposed for the Nakagami-m fading channel to find these performance metrics by simulations. Numerical results show that the outage performance and data rate of the cellular users are better in the proposed coordinated system than the conventional uncoordinated system.Read More
