New insights in optimal pilot symbol patterns for OFDM systems

Abstract

Nowadays, most wireless communication systems utilize coherent detection which implies the necessity of multiplexing reference symbols between data-symbols for the purpose of channel estimation. In Long Term Evolution (LTE), these reference symbols can consume up to 14.2% of the total bandwidth. In this work, we search for an optimal pilot-symbol pattern… (More)
