中文摘要：
提出一种复杂度低且性能良好的时频二维信道估计方法,在空间信道模型（SCM）一发一收天线配置下的仿真结果与理想信道估计时的误码率仅相差约2 dB,而算法复杂度为估计符号长度的线性关系,较极大似然估计的幂次关系有极大的降低。
英文摘要：
This paper proposed a channel estimation algorithm which has less complicacy and good performance. Simulation results of one transmitted and one received antenna in spatial channel model show that the giving method has almost 2 dB loss in bit error rate with the ideal channel estimation, but it has lower complexity than maximum likelyhood, that is linear versus exponential.
