Embodiment
[0029] In this embodiment, there are 4 transmit antennas (N T =4), 4 receiving antennas (N R =4), the modulation mode of the sending end is quadrature quadrature amplitude modulation, and the receiving end is a minimum mean square error equalizer, and the specific preprocessing steps are as follows:
[0030] Step 1, the receiving end obtains channel information at each subcarrier at the current moment according to an existing channel estimation method, and each channel information is a 4×4 complex matrix.
[0031] The channel estimation method is that the sending end sends pilot data at a specific time-frequency point, and the receiving end first obtains the channel information at the pilot point according to the received signal, and then estimates the channel information of all other subcarriers according to the channel estimation criterion. channel information.
[0032] Step 2, according to the size of the rank l of the channel information matrix H, determine the layer num...
