In OQAM/OFDM system,the coding scatter pilot channel estimation method has a high complexity. To solve this problem,we proposed a improved coding channel estimation method.Through reducing the code number in the pilot adjacent symbols and using the auxiliary pilot to cancel the interference in the other uncoded adjacent symbols in the pilot,this method reduced the coding method complexity efficiently.The simulation re-sults showed that the improved coding method had a lower complexity than coding method when the channel es-timation performance was close.%针对OQAM/OFDM系统基于预编码的离散导频信道估计复杂度较高的问题,提出了OQAM/OFDM系统改进的预编码信道估计算法.该算法通过减少导频周围预编码的个数,对未编码的干扰符号通过辅助导频法进行消除干扰,有效降低预编码方法的复杂度.仿真结果表明,改进的预编码方法与原方法相比在信道估计性能相近的情况下复杂度明显降低.
