Hybrid MU-MIMO spatial mapping using both explicit sounding and crosstalk tracking in a wireless local area network
摘要
說明書
Station transmission of station 302B begins in the baseband stage 542A where outgoing uplink communications to the WAP are subject to baseband transmit processing. The station transmits a single stream of data. The data is packetized in the packet assembler 552; encoded, scrambled, interleaved, and mapped to the appropriate constellation points in the encoder mapper 554, and sent to the spatial mapper 556 for any spatial mapping. In the instant example, where the station has only one antenna no spatial mapping is possible. The outgoing communication stream is then passed onto the OFDM tone/sub-channel bins 558A at the input of the IDFT component 558 which transform the outgoing communications from the frequency to the time domain. The outgoing communication data is then passed to the RF stage 542B for upconversion to the appropriate communication channel and transmission by the antenna 540.
