In order to estimate a transmission channel, a typical wireless communications system multiplexes a fixed pattern of symbols known at the receiver within the data-symbols. In Long Term Evolution (LTE), these reference symbols can consume up to 14.2% of the total transmission bandwidth. In this work, we investigate an optimal pilot-symbol pattern design using a post-equalization Signal to Interference and Noise Ratio (SINR) framework. We show how to choose the distance between adjacentdoi:10.1109/icc.2013.6655451 dblp:conf/icc/SimkoWR13 fatcat:27xsj7hstnflfhhthzmkghhege
