Abstract: |
|||
| An equalizer applied in a multiple input multiple output (MIMO) orthogonal frequency division multiplex (OFDM) system for alleviating interference among a plurality of received symbol blocks is disclosed. The equalizer includes: a matched filter for extracting a preliminary equalized signal vector from a received symbol block; a blocking device for generating a preliminary interference signal vector by attenuating a equalized signal vector from the received symbol block; a weighting device, electrically connected to the blocking device, for generating an interference signal vector by adjusting the preliminary interference signal vector; and a subtractor, electrically connected to the weighting device and the matched filter, for generating the equalized signal vector of the received symbol block according to the difference between the interference signal vector and the preliminary equalized signal vector. | |||
