Improving the efficiency of LTE using OFDM/OQAM

Abstract

Orthogonal Frequency Division Multiplexing modulation technique is used in the downlink of LTE. One of OFDM disadvantages is the outside of guard intervals (cyclic prefixes), which limits the date rate. The basic idea in this article is the increase in the LTE throughput using OFDM/OQAM. Two preamblebased channel estimation methods for OFDM/OQAM modulation systems are presented.
