Abstract
A wireless channel type detection method and apparatus. The type of a channel can be identified on the basis of at least one of carrier phase slope consistency, a ratio of phase differences of carrier phases at different times, and a carrier path loss, i.e., the type of the channel is determined to be LOS transmission or NLOS transmission. Thus, the precision of positioning resolution can be effectively improved.
