Pilot carrier and it's position?
I am trying to realize coherent OFDM using 16-QAM modulation Scheme using OptiSystem simulation platform. But, I am confused about what number of the pilot carrier should I use for better result considering 512/1024 subcarrier OFDM.
I found from literature that “Pilots are used to track the residual phase error if present after frequency correction. Without this correction, the constellation points start rotating either +ve/-ve angle. It is very much sensitive at higher constellation.” at http://www.edaboard.com/thread219563.html
