Abstract
One of 3rd Generation Partnership Projects's release 9 research areas is deployment and improvement of Long Term Evolutions's Evolved Universal Terrestrial Radio Access interface in local area cells, using time division duplex and 100MHz available bandwidth. For uplink part of this system, we revise and study MIMO algorithms considered in release 8's downlink (Cyclic Delay Diversity and Space-Frequency Block Codes open-loop schemes, Singular Value Decomposition and codebook-based closed-loop schemes), look for new alternatives, and simulate impacts of given scenario - reciprocity, correlated MIMO channels, slow fading etc. As a result, we draw conclusions about advantages of having multiple transmit antennas in User Equipment in contrast with higher price and power consumption.
