Abstract

The advances in multiple access techniques has been one of the key drivers in moving from one cellular
generation to another. Starting from the first generation, several multiple access techniques have been
explored in different generations and various emerging multiplexing/multiple access techniques are being
investigated for the next generation of cellular networks. In this context, this paper first provides a detailed
review on the existing Space Division Multiple Access (SDMA) related works. Subsequently, it highlights the
main features and the drawbacks of various existing and emerging multiplexing/multiple access techniques.
Finally, we propose a novel concept of clustered orthogonal signature division multiple access for the next
generation of cellular networks. The proposed concept envisions to employ joint antenna coding in order to
enhance the orthogonality of SDMA beams with the objective of enhancing the spectral efficiency of future
cellular networks.
