抄録

This paper proposes a new Zero-Padded CAZAC sequence by using a discrete chirp signal and proves mathematically that the proposed Zero-Padded CAZAC sequence satisfies the original properties of constant amplitude and zero-autocorrelation in the time domain. This paper also demonstrates the effectiveness of proposed Zero-Padded CAZAC sequence by using computer simulation results when employing it as a preamble symbol in the channel estimation method for the OFDM signal with a non-Nyquist sampling rate in the non-linear and multipath fading channels.
