qpsk: need help please.
hello,
In my code for qpsk i have passed the input signal through an fir filter having 6 coefficients.. the i/p signal was convolved with h(n). this leads to degradation of the signal.
Now i have been asked to remove the effect of this channel on the performance...
hi there,
i had mentioned earlier that i had done a tx n rx system simulatin qpsk system. i got the BER curve perfectly. my next task was to have the qpsk signal pass thru an FIR filter. I did that as well. and as expected the signal underwent distortion.
now i have been asked to the following...
i'm being asked to pass through the filter so that i can notice the difference.
the entire task is to pass the qpsk signal through the filter and then add noise to it.
hi.
I have written a code which emulates a qpsk tx n rx system. it works perfectly and i'm getting the BER curve exactly.
As my next task i have been asked to design an fir low pass filter through which i am to pass the qpsk signal. i'm not getting much assistance from the guide and i'm...
