Title: Innovations by Andreas Nevalainen in OFDMA Systems
Introduction
Andreas Nevalainen is a notable inventor based in Lund, Sweden. He has made significant contributions to the field of telecommunications, particularly in the area of Orthogonal Frequency Division Multiple Access (OFDMA) systems. His innovative work focuses on improving signal reception and reducing interference in communication systems.
Latest Patents
Andreas Nevalainen holds a patent titled "Uplink inter-carrier interference cancellation of OFDMA systems." This patent addresses the challenge of inter-carrier interference (ICI) in OFDMA systems receiving signals from multiple transmitters. The invention involves identifying the transmitted sub-carriers that contribute the most to ICI and removing their impact on the received signals. This can be achieved by calculating ICI terms based on the interfering sub-carrier and frequency offset or by demodulating the transmissions causing ICI and subtracting their effects from other signals. The effectiveness of this method depends on the relative strength of the sub-carriers and the degree of orthogonality lost due to factors such as frequency error and Doppler spread.
