The present invention provides a method for estimating a ratio of average chip energy to a total transmit power spectrum density (Ec/Ior), including: according to a group of spreading codes corresponding to an acquired spreading factor, obtaining an estimated value of Ior; according to a spreading code of a physical channel to be estimated, obtaining an estimated value of Ec; and according to the estimated value of the Ior and the estimated value of the Ec, obtaining an estimated value of EC/Ior. The present invention further provides a device for estimating Ec/Ior. By adopting the method and device for estimating Ec/Ior, when a base station adjusts transmit power of each physical channel, an adjusted value of Ec/Ior can be obtained in real time for accurate estimation. |
