1. A method in a wireless local area network (LAN) system, the method comprising:
generating a short training field (STF) signal for a frequency band, wherein the STF signal is generated based on an STF sequence which includes an M sequence; and
transmitting the STF signal on the frequency band,
wherein the M sequence is defined as M={−1, −1, −1, 1, 1, 1, −1, 1, 1, 1, −1, 1, 1, −1, 1}, and
wherein the STF sequence is a frequency-domain sequence, and wherein:
(i) for the frequency band corresponding to 80 MHz: the STF sequence is defined as {M, −1, M, −1, −M, −1, M, 0, −M, 1, M, 1, −M, 1, −M}*(1+j)/sqrt(2), and
(ii) for the frequency band corresponding to 40 MHz: the STF sequence is defined as {M,−1, −M, 0, M, −1, M} * (1+j)/sqrt (2),
wherein sqrt ( ) denotes a square root and “*” denotes multiplication.
