And it is combined with the forwarddifference prediction for the signal strength of next time to improve the handoff accuracy.
采用前向差分预测能够较准确地预测出下一时刻的信号强度,提高了切换触发速度和切换判决精度。

The accuracy and the existent problem of forwarddifference method are analyzed on the basis of comparing the transfer function of recursive formula with theoretical transfer function.
