Improved channel estimation for OFDM system with peak cancellation

This paper provides a new scheme to improve the channel estimation performance of peak cancellation (PC) aided orthogonal frequency division multiplexing (OFDM) system. The proposed scheme is based on a new PC signaling format characterized by mitigating the inference on the positions of pilot symbols. It achieves better channel estimation performance and hence to improve the system performance in fading channels without the increase of computational complexity.
