Multiple Input Multiple Output Detection Using Roulette Wheel Based Ant Colony Optimization Technique

This paper describes an approach to detect the
transmitted signals for 2×2 Multiple Input Multiple Output (MIMO)
setup using roulette wheel based ant colony optimization technique.
The results obtained are compared with classical zero forcing and
least mean square techniques. The detection rates achieved using
this technique are consistently larger than the one achieved using
classical methods for 50 number of attempts with two different
antennas transmitting the input stream from a user. This paves the
path to use alternative techniques to improve the throughput achieved
in advanced networks like Long Term Evolution (LTE) networks.
