摘　　要：现有的信道估计方法通常存在计算量大、复杂度高等问题。基于差分概率对信道衰落幅值进行概率统计,并将信道增益的时序关系及其时序差分量的概率统计特性相结合进行仿真实验,发现信道估计的计算量和复杂度得到了降低,并在此基础上提出基于差分概率的信道估计方法。The existed methods of channel estimation usually have expensive computations with high complexity.Probability and statistics of channel fading amplitude were exploited by differential probability.The computational complexity of channel estimation could be reduced by the simulations of combining time sequential relations of channel gain with probabilistic and statistical properties of time sequential difference components.Therefore,a method based on differential probability was proposed.
