The invention relates to interference cancellation in a receiver in a
radio system. The receiver receives at least two input data signals, and
extracts an interference estimate signal specific to each input data
signal. An interference estimate signal covariance matrix is calculated,
and autoregressive parameters and covariance parameters are estimated
from the covariance matrix. Interference is canceled from the at least
two input data signals by finite impulse response filters using the
estimated parameters as filter coefficients in the finite impulse
response filters.
