Abstract
According to the application needs of OFDM techniques, a new method of orthogonal frequency division multiplexing (OFDM) channel estimation based on inter symbol interference (ISI) cancellation was proposed. The channel estimation was based on circular convolution, after which a low-complexity frequency-domain ZF equalization was used. The performance of bit-error-rate (BER) was also simulated and analyzed under the additive-white-Gaussian-noise (AWGN) channel, Rayleigh fading channel with mobility. The simulation results showed that this method could be applied to the channels of time-varying environments, and could get better performance than the traditional cyclic prefix (CP)-OFDM.
