Abstract:
The invention relates to an apparatus comprising, a sampler configured to receive and sample a signal for producing signal samples; a first configured to receive or determinate a scaling factor for a reliability factor and to determine power or energy of an input signal of an interference canceller; a generator configured to generate an estimated replica of a transmitted desired signal by using the signal samples; a residual processor configured to subtract the estimated replica from the input signal of an interference canceller for generating a residual signal and to determine power or energy of the residual signal; and a divider configured to divide the power or energy of the residual signal by the power or energy of the input signal of an interference canceller and a multiplier configured to multiply a result of the division by the scaling factor of a reliability factor.
