Hi guys, I encountered a problem while using qammod(x,32) function (and higher, like 64 or 256). In fact, the received signal that I get is not in the same scale as the original one, thus making my decoding insufficient (my ber ratio is 0.25 so I guess that he gets like a half of the points correctly, the other half wrong). What can I do to resize the plot?
The received signal is after using the fft() function. The fft function makes my signal not as "stretched" as it should be.
