Abstract: In recent years, several smart antenna systems have been proposed, and demonstrated at the base station of wireless communication systems, and these have shown that significant system performance improvement is possible. In this paper, we consider the use of adaptive antennas at the base and mobile stations in combination with orthogonal frequency division multiplexing in both the down and uplinks. This system allows multiple user access in frequency subcarriers as well as space. Thus, it is also known as spatial- subcarrier multiple access. The advantages of the proposed system includes reductions in average error probability and increases in capacity. To demonstrate the potential of our proposed system, analytical along with Monte Carlo simulation results are provided.
