By a News Reporter-Staff News Editor at Telecommunications Weekly -- Research findings on Networks - Wireless Communications are discussed in a new report. According to news reporting out of Xuzhou, People’s Republic of China, by VerticalNews editors, research stated, “In this letter, we propose a novel pilot assignment scheme for the pilot contamination problem in massive multipleinput multiple-output multi-cell networks. Based on the asymptotic signal-to-interference-plus-noise ratio (SINR), the proposed pilot assignment scheme adopts the harmonic SINR utility function to quantify the fairness of all users in the network.”
Funders for this research include DoD, NSFC, NSF of Jiangsu Province, CUHKSZ Presidential Post-Doctoral Fellowship, NSF.
Our news journalists obtained a quote from the research from the China University of Mining and Technology, “Specifically, we formulate the pilot assignment problem as a minimum-weight multi-index assignment problem. For a two-cell network, this problem can be solved by the Hungarian algorithm with a strongly polynomial complexity. For the general multi-cell networks with more than two cells, this problem is in general NP-hard and we propose an efficient algorithm to obtain a suboptimal solution.”
According to the news editors, the research concluded: “The numerical experiments show that the proposed algorithms outperform other conventional pilot assignment schemes.”
