Abstract
The present disclosure provides a method for estimating OVSF (orthogonal variable spreading factor) code, the method comprises setting an initial value of a spreading factor and an initial value of an index of the spreading factor; extracting a first reception symbol by dechannelizing a reception signal based on a candidate OVSF code corresponding to the set spreading factor and the set index; acquiring a first code domain power of the first reception symbol; acquiring, if the first code domain power is greater than or equal to a predetermined reference value, variance of power of the first reception symbol which is normalized by the first code domain power; and estimating a used OVSF code based on the variance of the normalized power of the first reception symbol.
