A Novel Channel Estimation Method for TD-HSPA+ System in Rapidly Time-Varying Environments
This paper proposes a novel channel estimation method for TD-HSPA+ system in rapidly time-varying environments. We use a linear prediction model to depict the channel impulse response within a timeslot, then a least square (LS) and a minimum mean-square error (MMSE) estimator are deduced respectively based on some statistical characteristics of the channel. We further provide an approach to employ the proposed LS/MMSE method in downlink. As is proved by the simulations, the new estimation method outperforms other existing algorithms a lot. It’s also important to point out that the proposed method is both robust and computationally efficient.
