A technique weights noise power used in a demodulation/demapping process using on an estimate of interference and its associated power. Using this technique the effect of partial interference can be ameliorated. For example, a value, σ2, can be used to represent the estimated noise and interference power, and σ2 can be used to modify a received signal to ameliorate the effects of noise and interference. σ2 can be adjusted in response to partial interference, and can be represented by the formula: σ2=σN2+q σI2, where σN2 is “noise power,” σI2 is “interference power,” and q is an interference correction factor.
