Abstract
Wireless MIMO (multiple input multiple output) communication techniques are proposed to boost spectrum efficiency using antenna arrays so that broadband data such as multimedia signals can be transmitted over a limited bandwidth. The AM (autocorrelation matching) method is a SOS (second-order statistics) based blind MIMO-FIR equalization technique that may enable wireless MIMO communications without identifying MIMO-FIR channels. This paper presents a closed-form solution to computing the optimal zero-forcing equalizer for the AM method using the knowledge of second-order statistics of the transmitted signals and received signals. Numerical simulations are given to show the effectiveness of the AM method and the performance of the closed-form solution.
