MIMO seems to be the ultimate solution to increase the system capacity without requiring the need to additional spectral resources. In MIMO, multiple signals are transmitted instantaneously via enough spaced antennas. At the receiver side, the main challenge resides in designing signal processing techniques, i.e., detection techniques, capable of separating those Transmitted signals with acceptable complexity and achieved performance. Motivated by the importance of the detection techniques as an important factor in determining both the feasibility and performance of the MIMO systems, this study only considers the receiver structure for the MIMO techniques.
