摘要
This review paper envisages use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Various upcoming transmit strategies are discussed and compared to existing strategies such as beam forcing and space time block coding. It is revealed through this paper that the performance of transmission algorithm is largely dependent on channel characteristics such as the number of transmit & receive antennas & the existence of the line of sight component. The effects of non-linear transmit amplifiers In array antennas sire also reviewed. The use of switchable directional properties of the switched parasitic antenna, is studied in a MIMO context & compared to array techniques. It Is found that it has comparable performance at a fraction of the cost for an array antenna.
