In receiving equipment such as a mobile terminal (1) for decoding received signals coded according to a CDMA method are decoded in an intermediate processor (9). In the decoding, coefficients or elements of a vector w are calculated in a unit or module (13) by an iterative method as a solution to a system of linear equations represented by the matrix equation Rw = h, where R is a matrix of known elements and h is a known vector. For terminating the iteration, a value of the signal to interference plus noise ratio SINR for the received signals is calculated in each iteration step and then this calculated value or a quantity derived therefrom is used as a stopping criterion or generally in a stopping algorithm.
