Patent number: 9319166Abstract: In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.Type: GrantFiled: September 26, 2012Date of Patent: April 19, 2016Assignee: Intel CorporationInventors: Alexey Vladimirovich Khoryaev, Artyom Lomayev, Alexander Alexandrovich Maltsev, Vladimir Kravtsov, Michael Genossar

Publication number: 20140270015Abstract: An approach is provided to compensate for inter-carrier interference caused by phase noise in a transmitted or received signal. The approach involves causing an estimation of one or more phase noise spectrum taps that cause inter-carrier interference in a received signal. The approach also involves causing an approximation of an instantaneous phase noise spectrum by a low order finite impulse response filter based on the estimated one or more phase noise spectrum taps. The approach additionally involves determining a de-convolution filter having two or more filter coefficients for one or more orthogonal frequency-division multiplexing symbols associated with the received signal. The approach further involves causing the de-convolution filter to be matched to the approximated instantaneous phase noise spectrum.Type: ApplicationFiled: June 28, 2012Publication date: September 18, 2014Inventors: Vladimir Kravtsov, Michael Genossar, Alexey Khoryaev, Artyom Lomayev
