Method for Determining Candidate Line of Sight Path and Wireless Local Area Network Device

A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a wireless local area network (WLAN) device to:

• receive a signal, wherein the signal comprises radio signals received from a to-be-identified terminal and through a plurality of paths, wherein the radio signals respectively comprise first training sequences, and wherein the signal further comprises a superposition of the first training sequences;
• match the signal and a second training sequence to obtain time points at which the first training sequences are received, wherein the second training sequence is stored in the WLAN device, wherein the first training sequences and the second training sequence have a same value, and wherein the time points comprise a first time point of a first training sequence an earliest-received radio signal;
• and
• determine a path of the earliest-received radio signal as a candidate line of sight (LOS) path.

A wireless local area network (WLAN) device comprising:

• an antenna configured to receive a signal, wherein the signal comprises radio signals received from a to-be-identified terminal and through a plurality of paths, wherein the radio signals respectively comprise first training sequences, and wherein the signal further comprises a superposition of the first training sequences;
• a memory configured to store a second training sequence, wherein the first training sequences and the second training sequence have a same value;
• and
• a processor coupled to the antenna and the memory and configured to:
• match the signal and the second training sequence to obtain time points at which the plurality of first training sequences are received, wherein the time points comprise a first time point of a first training sequence of an earliest-received radio signal;
• and
• determine a path of the earliest-received radio signal as a candidate line of sight (LOS) path.
