Claim 6:
7. An uplink multi-station channel estimation method, applied to an access point (AP) communicating with a plurality of stations (STAs), the uplink multi-station channel estimation method comprising:
receiving, by the AP, a frame sent by each STA of the plurality of STAs, the frame comprising a first group of training sequences and a second group of training sequences;
calculating a frequency offset value between the each STA and the access point AP to generate a plurality of frequency offset values, the calculating using the first group of training sequences and the second group of training sequences; and
performing, by the AP, channel estimation based on the plurality of frequency offset values between the plurality of STAs and the AP.
