i wanted to know that does the change in the location of pilot carriers in OFDM Symbol cause any effect on the BER vs SNR plot ?
i have FFT size 64 and 4 pilots with the location 13,26,39,52.
now i wanted to change the location to 7,21,35 and 49 for pilots for same fft size.
but when change made its not working.
can anyone tell me where i m going wrong . and does location of pilots really matters?
The answer to your question "will the location of pilot affect the performance " is yes! But I think this is true in one situation that you have frequency selective fading channel. In another case, if you use pilot to compensate timing offset, carrier offset or conduct channel estimation, this will also affect the performance.
and sir can you provide any ieee paper related to this disscussion ?
these are lot many questions ,i know .thanks in anticipation for your response :)
@ Joel .Thanks a lot sir for your kind response.its a great help for me.
