What is the MIMOchannel coefficient?

I try to use comm.MIMOChannel object from its example code.

The MIMO channel is created with:

hMIMO = comm.MIMOChannel('RandomStream', 'mt19937ar with seed',...
'PathGainsOutputPort', true, 'MaximumDopplerShift', 0, 'Seed', 70)

The fading channel is a flat, constant type in the above settings.

It is used to filter through the channel, add noise and decode:

[yFad, yPG] = step(hMIMO, yTx); % Transmit over MIMO fading channel
yRec = step(hAWGN, yFad); % Add receiver noise
rxBits = step(hSpDec, yRec, squeeze(yPG)); % Decode received signal

Before I am preparing to implement a decoder in FPGA, I want to know that what the channel is. I guess that it should look like an FIR coefficients, but I do not find how to get it. Could you help me?
