NB-IOT RECEIVER OPERATING AT A MINIMUM SAMPLING FREQUENCY Russian patent published in 2019 - IPC H04L27/26 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. Method includes receiving a plurality of radio signal samples obtained by digitizing an OFDM symbol with a reduced sampling frequency, wherein the reduced sampling rate causes intersymbol jitter between a plurality of OFDM symbols. Method further includes determining a sampling offset corresponding to a symbol number for the OFDM symbol, converting the OFDM symbol samples to a plurality of frequency domain resource elements and determining a phase shift for each of the resource elements using the sampling offset. Further, said method reduces symbol-to-symbol jitter by rotating each resource element using an appropriate phase shift to generate resource elements with phase rotation. Device has a corresponding narrow-band wireless communication receiver, a narrow-band wireless communication receiver, a jitter compensation circuit and a computer program product.

EFFECT: technical result consists in reduction of intersymbol jitter caused by processing of each of multiple OFDM symbols in the received signal.
