MIMO Transmission Schemes for LTE and HSPA Networks

[rmwambu]

For over a decade universities and wireless research labs have been combining multiple antenna transmission techniques with advanced signal processing algorithms to create what is sometimes called smart-antenna and is also known as multi-input multi-output (MIMO) technology. These schemes are now moving into mainstream communication systems. Indeed, MIMO technologies can already be found in wireless local area network access points (e.g. 802.11n based solutions). This has led to MIMO being standardized in WiMAX as well as in 3GPP Rel-6 and Rel-7 of the UTRAN (HSPA) specifications. Further, Rel-8 of the E-UTRAN (LTE) 3GPP specifications, completed in March 2009, included the most advanced forms of MIMO in any standard in the industry. And even more advanced MIMO enhancements are currently being studied for inclusion in 3GPP Rel-9 and Rel-10. GET FURTHER INSIGHTS FROM: http://trends-in-telecoms.blogspot.c...r-lte-and.html
