| Abstract(in English) | Diversity reception is a powerful technique to reduce the degradation of transmission quality caused by fading. One of the techniques, postdetection maximal-ratio combiner (MRC) is not always effective under cochannel interference, because received signal strength used as the weighting factor is not relative to the signal to interference power ratio (SIR). This report proposes a SIR estimation method and a diversity scheme using the estimated SIR as the weighting factor. In this scheme, instantaneous SIR is estimated by desired signal strength that is measured using the matched filter output. The performances are evaluated theoretically and computer simulations. The results show that the proposed SIR estimation method can estimate the accurate instantaneous SIR and the BER characterisitics of the proposed diversity scheme under cochannel interference realize better performances than those of MRC. |
