- W2358082827 abstract "In LTE-advanced system,when space orthogonal-resource transmit diversity( SORTD) is used on PUCCH,the UE transmits the same control information from different transmit antennas with different cyclic shifts. By exploiting the properties of reference signals( RS),we find a special form of signal model. Based on the special form,firstly,we propose a low complexity channel estimator based on LS and spline. Then,to improve the interpolation performance we propose a LS and DCT based approach. For their limited performance,we derive a more accurate channel estimator based on MMSE and DCT. Finally,the performance of the proposed channel estimation is verified via simulation. As a result,the MMSE and DCT based approach has the best performance." @default.
