Wireless reception with combination ratio calculation

A wireless receiver device (101) demodulates single-carrier signals, transforms the received signals in time-domain into frequency-domain (101-1,2), calculates a combination ratio by referring to a ratio of an interference power and a noise power (105), and uses an equalisation weight calculator means (106) for generating an equalisation weight by combining a noise-plus-interference power identity matrix (103) and an interference correlation matrix (104) in accordance with the combination ratio. The noise and interference powers may be obtained from a power spectrum density of the received signals. The power identity matrix is claculated using channel estimates (102). In another embodiment, the ratio is calculated using an iterative optimisation technique instead of using the noise and interference power (fig.4, not shown).
