Hi all,
I recenly join this group and i hope this will be a good plateform for me to
share my ideas with others.
I am doing SNR estimation with color noise for OFDM systems.i am confused about
somthings so i am writing here.i am very thanksful for your kind replies.
I take 256 bit symbol after adding cyclic prefix 'cp=1/4' its length
becomes 320.
For color noise estimation i divide the whole band into subbands of 16 so they
become 20 sub bands.
Than i transmit each band through releigh channel.lets supose the recieved
signal after each channel is Y.
than i add color noise in each of the branch.color noise is generated by passing
white noise through FIR1 filter.
then
recieved signal with colour noise becomes Y+color noise.
Noise power is estimated against every subband and then averaged over all OFDM
symbol.
can anybody guide me how to final noise power in each band and how to find
signal power ?
Thanks in advance for your opinion.
Rana
