Optimal VLSI architecture for a 2x2 MIMO detector -

Abstract

In communications systems, increasing the data rate of transmission has become a vastly growing field of study. Multiple-Input Multiple-Output systems emerged as a promising approach in such a field. However, increasing the number of transmitted vectors makes the detection issue even harder. At the transmission side, the data is changed into a binary sequence of bits to be later modulated. Then, the signal is sent over the channel where some noise will be added to the signal distorting it. At the receiver side, the receiver receives these noisy symbols displaced from their initial position in the constellation. Therefore, recovering the original symbol coordinates on the constellation is not an easy task especially when there are multiple transmission sources and multiple receivers. In this thesis, we consider 2x2 MIMO system and we propose an efficient detection method whose architecture was implemented in VHDL.
