Transceiving method for phase noise compensation in SC-FDE scheme, and apparatus therefor

An operation method of a transmitting apparatus for transmitting data in a single carrier frequency domain equalization (SC-FDE) scheme, the operation method comprising:

• transmitting an N-th data block belonging to a frame including a plurality of data blocks to a receiving apparatus, each of the plurality of data blocks including a data period and a unique word (UW) period, and N being an integer greater than or equal to 1;
• and
• transmitting an (N+1)-th data block belonging to the frame to the receiving apparatus,
• wherein the receiving apparatus estimates a phase noise in a time domain by combining a first UW transmitted in a UW period of the N-th data block and a second UW transmitted in a UW period of the (N+1)-th data block, a time domain compensation for the estimated phase nose is applied to the (N+1)-th data block, and the first UW and the second UW are configured with a same sequence, and configured to have a same UW period length.

A receiving apparatus for receiving data in a single carrier frequency domain equalization (SC-FDE) scheme, the receiving apparatus comprising:

• a processor;
• a memory storing instructions executable by the processor;
• and
• a transceiver controlled by the processor,
• wherein when executed by the processor, the instructions cause the processor to:
• receive an N-th data block belonging to a frame including a plurality of data blocks from a transmitting apparatus through the transceiver, each of the plurality of data blocks including a data period and a unique word (UW) period, and N being an integer greater than or equal to 1;
• store a first UW received in a UW period of the N-th data block in a buffer;
• receive an (N+1)-th data block belonging to the frame from the transmitting apparatus through the transceiver;
• estimate a phase noise in a time domain by combining the first UW with a second UW received in a UW period of the (N+1)-th data block;
• and
• apply time-domain compensation according to the estimated phase noise to the (N+1)-th data block, and demodulate data of the (N+1)-th data block,
• wherein the first UW and the second UW are configured with a same sequence, and configured to have a same UW period length.
