Abstract
A device, method, and non-transitory computer readable medium to perform a method of blind equalization implemented by a filter bank multi-carrier with offset quadrature amplitude modulation (FBMC-OQAM) transmission system. A first matrix W is obtained by dividing a second matrix V by a receiver waveform matrix G. The second matrix V is obtained by calculating a total objective function J until the total objective function J is either constant or below a threshold error margin. The calculation of the total objective function J includes iterating calculations with a plurality of combination of a frequency bin p and a time slot q. Weights of the obtained first matrix W are applied to an equalizer. A received signal in the equalizer is processed using the applied weights. The weights of the obtained first matrix W are configured to minimize a total outage probability Pout, TOTAL.
