摘要

研究了AWGN信道上OFDM/OQAM系统的联合载波频偏和信道估计问题。特别是，作为初步检测，首先推导了基于无条件ML估计的载波相位偏移估计。在此基础上，为了提高载波频偏估计的精度，提出了基于前言的数据辅助估计方法。最后，根据接收信号的形式估计信道脉冲响应。通过计算机仿真对所提方法的性能进行了评估;实验结果证明了该方法的有效性。

Joint Carrier Frequency Offset and Channel Estimation for OFDM/OQAM Systems on AWGN Channel

The paper investigates the problem of joint carrier frequency offset and channel estimation for OFDM/OQAM systems on AWGN channel. In particular, as the preliminary detection, carrier phase offset estimation based on unconditional ML estimator is derived at first. On this basis, in order to improve the accuracy of carrier frequency offset estimation, data-aided method based on the preamble is proposed. Finally, channel impulse response is estimated based on the form of the received signal. The performance of the proposed method is assessed via computer simulations; the results prove the effectiveness of the method.
