wherein the second phase rotation value is a phase rotation value obtained by repeating a phase rotation value that is defined for an 80 MHz band in an 802.11ax system,
wherein the third phase rotation value is a phase rotation value being defined in 80 MHz band units in the 320 MHz band based on optimal PAPRs of the L-STF and the L-LTF,
wherein the second rotation phase value is [1 −1 −1 −1 1 −1 −1 −1 1 −1 −1 −1 1 −1 −1 −1],
wherein, among the second rotation phase value, a first value 1 is applied to subcarriers having subcarrier indexes from −512 to −449,
wherein, among the second rotation phase value, a second value −1 is applied to subcarriers having subcarrier indexes from −448 to −385,
wherein, among the second rotation phase value, a third value −1 is applied to subcarriers having subcarrier indexes from −384 to −321,
wherein, among the second rotation phase value, a fourth value −1 is applied to subcarriers having subcarrier indexes from −320 to −257,
wherein, among the second rotation phase value, a fifth value 1 is applied to subcarriers having subcarrier indexes from −256 to −193,
wherein, among the second rotation phase value, a sixth value −1 is applied to subcarriers having subcarrier indexes from −192 to −129,
wherein, among the second rotation phase value, a seventh value −1 is applied to subcarriers having subcarrier indexes from −128 to −65,
wherein, among the second rotation phase value, an eighth value −1 is applied to subcarriers having subcarrier indexes from −64 to −1,
wherein, among the second rotation phase value, a ninth value 1 is applied to subcarriers having subcarrier indexes from 0 to 63,
wherein, among the second rotation phase value, a tenth value −1 is applied to subcarriers having subcarrier indexes from 64 to 127,
wherein, among the second rotation phase value, an eleventh value −1 is applied to subcarriers having subcarrier indexes from 128 to 191,
wherein, among the second rotation phase value, a twelfth value −1 is applied to subcarriers having subcarrier indexes from 192 to 255,
wherein, among the second rotation phase value, a thirteenth value 1 is applied to subcarriers having subcarrier indexes from 256 to 319,
wherein, among the second rotation phase value, a fourteenth value −1 is applied to subcarriers having subcarrier indexes from 320 to 383,
wherein, among the second rotation phase value, a fifteenth value −1 is applied to subcarriers having subcarrier indexes from 384 to 447, and
wherein, among the second rotation phase value, a sixteenth value −1 is applied to subcarriers having subcarrier indexes from 448 to 511.
