摘要：
To the channel estimation problems of offset quadrature amplitude modulation/orthogonal frequency division multiplexing (OQAM/OFDM) systems, this paper proposed an iterative scattered pilot channel estimation method. Through analysis the intrinsic imagine interference, this paper indicated to the low performance problem with common scattered pilot channel estimation methods. This paper decreased the number of the data symbol that whose interference canceled by the auxiliary pilot, and utilized an iterative process to cancel the interference of other data symbols. The simulation results shown that the proposed method has a better channel estimation performance when the auxiliary pilot power is the same as average data power.
