Abstract :
The work presented in this proposal analyzes the effect of the pilot location process over both the time, and frequency directions within the OFDM frames. The optimum time-frequency pilot spacing that minimize the mean square error of the channel estimated has been analytically designed, and the system performance analyzed in terms of bit error rate using different bi-dimensional interpolation filters
