Alexey Vladimirovich Khoryaev, Artyom Lomayev, Alexander Alexandrovich Maltsev, Vladimir Kravtsov, Michael Genossar: Method and apparatus for inter-carrier interference mitigation in phase noise limited wirelss communiction systems. Intel Corporation, Schwegman Lundberg & Woessner P A, April 19, 2016: US09319166 (2 worldwide citation)

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 ...

Vladimir Kravtsov: Reducing phase noise in phase-encoded communications signals. Intel Corporation, Trop Pruner & Hu P C, May 8, 2007: US07215705 (1 worldwide citation)

A receiver may reduce phase noise in phase-encoded communications signals using symmetrical averaging to estimate phase shift correction. In one embodiment, a receiver, such as a quadrature amplitude modulation receiver may include a decision feedback equalizer and a filter of low complexity to rece ...

Vladimir Kravtsov: System and method of improving power efficiency in wireless communication system. INTEL CORPORATION, April 4, 2017: US09615326

An apparatus may comprise a signal mapper to map a pre-emphasized signal to sub-carriers symmetrically about DC, and a peak-to-average-power reduction (PAPR) module arranged to receive a pre-emphasized signal and treat the pre-emphasized signal so as to reduce PAPR in a transmit signal sent from the ...
