Claim 4:
5. A transmitting apparatus of a wireless local area network, LAN, system, comprising:
a transceiver transmitting and/or receiving a wireless signal; and
a processor controlling the transceiver,
wherein the processor is configured to:
generate a short training field, STF, signal; and
transmit, via the transceiver, the STF signal to a receiving apparatus via 80 MHz band,

wherein the STF signal is generated based on a STF sequence defined as shown below:
{M, 1, −M, 0, −M, 1, −M}*(1+j)/sqrt(2), wherein ‘sqrt( )’ denotes a square root, ‘j’ denotes an imaginary number, and ‘*” denotes multiplication, and
wherein the M sequence is defined as shown below:

M={−1,−1,−1,1,1,1,−1,1,1,1,−1,1,1,−1,1}.
