Abstract :
We present new carrier frequency acquisition and channel estimation algorithms for OFDM systems. Both new algorithms utilize only one training frame to carry out carrier frequency acquisition and channel estimation at the same time. The simulation results show that both algorithms are immune from timing error with a high precision and low computational complexity.
