Method for estimating power in a CDMA receiver |
摘要 |
The invention relates to a method for estimating power in a CDMA telecommunications system, in which method a sample set is formed (300) from the received signals. The proposed method reiterates (302 to 312) the following steps, until a predetermined ending condition is fulfilled: forming (302) an absolute value set from the absolute values of sample set elements, setting (304) a threshold value; calculating (306) a reference value by multiplying the mean of the absolute value set by the threshold value; comparing (308) the element of the absolute value set with the reference value and forming (312) a second sample set by deleting elements exceeding the reference value from the sample set; the ending condition being fulfilled, estimating (314) the power on the basis of the remaining sample set. <IMAGE> |
