Abstract
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-generation (4G) communication system, such as long-term evolution (LTE). An operation method of a transmitter in a wireless communication system is provided. The method includes applying a filter to data, mapping the data to which the filter is applied to at least one subcarrier, and transmitting the mapped data to a receiver. The filter is determined based on based on the allocated resource.

Claim
1. A method for operating a transmitter in a wireless communication system, the method comprising:
applying a filter to data;
mapping the data to which the filter is applied to at least one subcarrier; and
transmitting the mapped data to a receiver,
wherein the filter is determined based on a receiver characteristic and reception performance of the receiver, and
wherein the filter includes, as at least one coefficient, at least one value obtained by sampling a predetermined polynomial a number of times equal to a number of at least one symbol if a number of the at least one subcarrier is a same as the number of the at least one symbol included in the data.
2. The method of claim 1,
wherein the filter includes, as the at least one coefficient, at least one value obtained by sampling the predetermined polynomial a number of times equal to a number of the at least one subcarrier if the number of the at least one subcarrier is greater than the number of the at least one symbol.
3. The method of claim 1, wherein the applying of the filter to the data comprises:
changing a phase of at least one symbol included in the data based on an amount of phase rotation of the at least one symbol, and
filtering, using the filter, the data including the at least one symbol, the phase of which is changed.
4. The method of claim 3,
wherein the amount of phase rotation is determined based on a number of the at least one symbol if a number of the at least one subcarrier is a same as the number of the at least one symbol, and
wherein the amount of phase rotation is determined based on the number of the at least one symbol and the number of the at least one subcarrier if the number of the at least one subcarrier is greater than the number of the at least one symbol.
5. The method of claim 1, wherein the filter includes a circular convolution filter determined based on a number of at least one symbol included in the data.
6. A transmitting apparatus in a wireless communication system, the transmitting apparatus comprising:
a transmitter; and
at least one processor coupled with the transmitter,
wherein the at least one processor is configured to control to:
apply a filter to data,
map the data to which the filter is applied to at least one subcarrier, and
transmit the mapped data to a receiver, and
wherein the filter is determined based on characteristic of a receiver and reception performance of the receiver, and
wherein the filter includes, as at least one coefficient, at least one value obtained by sampling a predetermined polynomial a number of times equal to a number of at least one symbol included in the data if a number of the at least one subcarrier is a same as the number of at least one symbol.
7. The transmitting apparatus of claim 6,
wherein the filter includes, as the at least one coefficient, at least one value obtained by sampling the predetermined polynomial a number of times equal to the number of the at least one subcarrier if the number of the at least one subcarrier is greater than the number of at least one symbol.
8. The transmitting apparatus of claim 6, wherein the at least one processor is further configured to control to:
change a phase of at least one symbol included in the data based on an amount of phase rotation of the at least one symbol, and
filter, using the filter, the data including the at least one symbol, the phase of which is changed.
9. The transmitting apparatus of claim 8,
wherein the amount of phase rotation is determined based on a number of the at least one symbol if a number of the at least one subcarrier is a same as the number of the at least one symbol, and
wherein the amount of phase rotation is determined based on the number of the at least one symbol and the number of the at least one subcarrier if the number of the at least one subcarrier is greater than the number of the at least one symbol.
10. The transmitting apparatus of claim 6, wherein the filter includes a circular convolution filter determined based on a number of at least one symbol included in the data.
11. A receiving apparatus in a wireless communication system, the receiving apparatus comprising:
a receiver; and
at least one processor coupled with the receiver,
wherein the at least one processor is configured to control to:
receive data from a transmitter,
apply a transformation matrix, and
decode data to which the transformation matrix is applied,
wherein the transformation matrix is determined based on a filter shared by the transmitter and the receiver,
wherein the filter is determined based on characteristic of the receiver and reception performance of the receiver, and
wherein the filter includes, as at least one coefficient, at least one value obtained by sampling a predetermined polynomial a number of times equal to a number of at least one symbol included in the data if a number of at least one subcarrier allocated to the transmitter for transmitting the data is a same as the number of at least one symbol.
12. The receiving apparatus of claim 11,
wherein the filter includes, as the at least one coefficient, at least one value obtained by sampling the predetermined polynomial a number of times equal to the number of at least one subcarrier if the number of at least one subcarrier is greater than the number of at least one symbol.
13. The receiving apparatus of claim 11, wherein the at least one processor is further configured to control to:
change a phase of at least one symbol included in the data based on an amount of phase rotation of the at least one symbol, and
decode the at least one symbol, the phase of which is changed.
14. The receiving apparatus of claim 13,
wherein the amount of phase rotation is determined based on a number of the at least one symbol if a number of at least one subcarrier allocated to the transmitter is a same as the number of the at least one symbol, and
wherein the amount of phase rotation is determined based on the number of the at least one symbol and the number of the at least one subcarrier if the number of the at least one subcarrier is greater than the number of the at least one symbol.
