Abstract
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, σ, can be used to represent the estimated noise and interference power, and σcan be used to modify a received signal to ameliorate the effects of noise and interference. σcan be adjusted in response to partial interference, and can be represented by the formula: σ=σ+q σ, where σis 'noise power,' σis 'interference power,' and q is an interference correction factor.
