A perspective on Channel estimation in MIMO-OFDM wireless systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Orthogonal frequency division multiplexing (OFDM) is a multiplexing technique which is widely applied in wireless communication systems because of its high data rate transmission capability and high bandwidth efficiency. This paper presents a comprehensive survey on OFDM for wireless communications. This survey will first review basic OFDM modulation along with techniques to improve the performance of OFDM in wireless communication. The combination of multiple-input multipleoutput (MIMO) and OFDM has the potential to address the problem of interference in modern communication systems, and therefore particular emphasis is given to MIMO-OFDM. It also includes channel estimation which is essential for diversity combining in MIMO-OFDM systems. We conclude with the wireless applications of MIMO- OFDM systems.
