The downlink synchronization includes: deciding a range of downlink training sequence timeslot (DwPTS) based on training sequence power characteristic window value method; solving correlation of received data and training sequence in the range to obtain accurate receiving position of a UE. The correction of carrier deviation between a UE and the base station includes: estimating carrier deviation between a UE and the base station by software, recovering carrier frequency difference by using decision and feedback method to adjust hardware and carrier deviation correction method based on joint detection to correct carrier deviation.

Abstract: The invention relates to a method for improving smart antenna array coverage. Arbitrary beam forming of an antenna array can be implemented by adjusting n antenna units beam forming parameter W(n), based on difference of size and shape between coverage required in engineering design and actually realized coverage. The method includes: setting an accuracy of W(n), i.e. an adjusting step length, setting a set of initial values W0(n), an initial value of mean-square error &egr;0, setting counting variable, setting threshold of ending adjustment M and maximum emission power of an antenna unit T(n). With the settings, a loop for W(n) adjustment is executed. A step-by-step approximation method is deployed for adjusting antenna radiation parameters, based on the minimum mean-square error criterion. Finally, an actual coverage of an antenna array approximates to the required coverage, under local optimization condition.
