Figure 3From: Interference-free SDMA for FBMC-OQAM Precoder computation accuracy. Mean square error (MSE) as a function of the dimension N of the matrix model used to compute the precoder for a varying number of subchannels. Solid lines: pulse shaping filter of roll-off 1 for M varying; dashed line: pulse shaping filter of roll-off 0.5 for M=64. Parameters: N T =4, N R =3.Back to article page
