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 task,
1. i should generate h, which is the impulse response. i have to generate 6 coefficients. i know to do that but i'm asked to generate them with variances of 1, 1/2, 1/3, 1/4, 1/5, 1/6.
i should also be normalised such that summation Hi square = 1.
2. i have to then convolute it with the input signal x.
3. then for every 500 samples i have to change the coefficients, should do this 30 times.
4. finally from the h coefficients i should try and get bak the original signal.
coul some1 plz plz plz help with the following tasks listed above.. i would be greatful.
thank you.
regards,
shubro
