LTE Downlink Channel Estimation Using Music Algorithm
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 7
Abstract
3GPP LTE is the evolution of the UMTS in response to ever‐increasing demands for high quality multimedia services according to users’ expectations. Since downlink is always an important factor in coverage and capacity aspects, special attention has been given in selecting technologies for LTE downlink. This paper aims at channel estimation for LTE downlink using music algorithm. Music algorithm is an efficient technique used for frequency response estimation in far spaced channels .Maximum likelihood estimation haven been evaluated for different channel models in LTE downlink. Performance of music algorithm has been measured in terms of Bit Error Rate (BER) and Symbol Error Rate (SER).
