Description
Summary:ICI self-cancellation algorithms are promising techniques to mitigate the ICI effect in OFDM systems caused by high mobility. In the area of ICI self-cancellation, the calculation of optimum combining weight is still an open question. In this paper, the problem of finding optimum combining weight to minimize the ICI-plus-noise power is formulated. We then derived a noniterative algorithm to find the optimum solution.We also compare the performance of the optimum combining weight with other existing combining weight methods.
