Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a WLAN communication technology. Background technique [0002] A wireless local area network (Wireless Local Area Network, WLAN) is currently widely used in home gateways and enterprise networks. Now the carrier-level WLAN has taken shape, providing WLAN broadband services for WLAN-enabled mobile phones or WLAN-enabled tablet computers in outdoor areas. [0003] Modern digital communication systems, including WLAN, use Orthogonal Frequency Division Multiplexing (OFDM) to help the system achieve communication in multipath reflection and / or strong interference environments, and configure receivers to choose to work in increased capacity mode and and / or increased distance mode; the receiver can select two or more antennas to receive more than one sub-channel in the OFDM channel; combining techniques such as maximum ratio combining can help to process the symbol-modulated carri...
