Abstract

It is important to estimate the channel quality of forward link in cdma2000 1x EV-DV for much better systems performance. Two channel quality indicator algorithms are proposed in this paper. The CQI prediction based on the nonlinear numerical approximation is to get the parameters of the nonlinear numerical approximation model according to several past values of CQI information. And then we can employ this model to predict the coming CQI value. Another CQI prediction algorithm is based on the N-LMS algorithm according to the past CQI values. The simulations of the novel algorithms are performed to compare with the analysis. It is shown that the two algorithms have better performance than the general CQI processing method.
