rs generator polynomial
RS(255, 239) just tells you how many redundant symbols have been added by the encoder, the generator polynomial is normaly described in Octal form.
demodulation qpsk
you can use demod function in Matlab with 'pm' option if your data is available in Matlab workspace. For further info look at the documentation available on 'demod' function.
Re: ofdm project
OFDM is much bigger topic you need to be more specific about which aspect of OFDM you like to look into and come up with a project idea.
Hi,
Half band filter is also a lowpass FIR filter. The bandwidth of the filter is half of the Nyquist rate or quarter of the sampling rate and it makes half of the filter coefficients zero. The name 'Half-Band' comes from the fact it is using only half of the available bandwidth.
I hope it has...
The number of output bits in sigma-delta converter depends upon the bandwidth and the sampling rate, higher the oversampling ratio (Sampling Rate/bandwidth) the more bits (wordlength) you may achieve.
If you are just doing the transform the sampling frequency is unchanged however if you are doing any compression using DWT then there will be change in sampling frequency.
I hope this helps.
Can you please provide more info, what OFDMA standard are you talking? You need to know the pilot distribution, number of users, active and virtual carriers etc.
generate rayleigh from the uniform
Rayleigh fading can easily by generated by first generating White Gaussian noise (complex) and then applying filtering depending upon the Doppler spread. There is also anotherway using Jake's model.
Re: crame rao
CRB gives the minimum estimation error variance for a given estimator. There is excellent book called Digital Receiver Design by Mayer and Aschied.
Re: Low delay filters
First thing is that you dont need to have a sampling rate of 20MHz for a bandpass signal with carrier frequency of 10MHz! This is a common mis-understanding, the Nyquist theorem states the sampling rate has tobe equal or greater than the signal bandwidth. You may need to...
