Abstract:
The solution presented herein discloses a method of reducing inter-symbol jitter caused while processing each of a plurality of OFDM symbols in a received signal. For each of the plurality of OFDM symbols, the method comprises receiving a plurality of radio samples produced by a sampling of an OFDM symbol at a reduced sampling rate, where the reduced sampling rate causes inter-symbol jitter between the plurality of OFDM symbols. The method further comprises determining a sample offset corresponding to a symbol number for the OFDM symbol, transforming the samples of the OFDM symbol into a plurality of frequency-domain resource elements, and determining a phase offset for each of the resource elements using the sample offset. The method then reduces the inter-symbol jitter by rotating each resource element using the corresponding phase offset to generate phase-rotated resource elements. Corresponding narrow-band wireless receiver, narrow-band wireless receiver apparatus, jitter compensation circuit and computer program product are also disclosed.

Claim (Index 41):
A narrow-band wireless receiver configured to reduce inter-symbol jitter caused while processing each of a plurality of Orthogonal Frequency Division Multiplex (OFDM) symbols in a received signal, the narrow-band wireless receiver comprising:\n a receiver interface circuit configured to, for each of the plurality of OFDM symbols, receive a plurality of radio samples produced by a sampling of an OFDM symbol at a reduced sampling rate, where the reduced sampling rate causes inter-symbol jitter between the OFDM symbols; a frequency transformation circuit configured to, for each of the plurality of OFDM symbols, transform the samples of the OFDM symbol into a plurality of frequency-domain resource elements; and a jitter compensation circuit configured to, for each of the plurality of OFDM symbols:\n determine a sample offset corresponding to a symbol number for the OFDM symbol, said sample offset representing a difference between an actual sample start time and a desired sample start time; \n determine a phase offset for each of the resource elements using the sample offset; and \n reduce the inter-symbol jitter by rotating each resource element using the corresponding phase offset to generate phase-rotated resource elements.
