how to control the Tx rate? #43

Open liucc07 opened 4 years ago

liucc07 commented 4 years ago

I use the TL-WD4310 for Tx and Rx to obtain CSI. The TL-WD4310 is equipped with three antenna, but only two can be used in 2.4G band, three can be used in 5G bang, as can be seen from the drive info: "Available Antennas: TX 0x3 RX 0x3 Configured Antennas: TX 0x3 RX 0x3" for phy0 and " Available Antennas: TX 0x7 RX 0x7 Configured Antennas: TX 0x7you chose RX 0x7" for phy1.

what does not make sense is the CSI matrix is always of the size 2256 for 2.4G 20M BW, no matter which mcs rate you choose(the matrix element is not zero). In fact, if when the single stream MCS rate is selected, the CSI matrix should be of the size 1256.

Anyone knows why?
