| Abstract(in English) | Frequency-domain equalization (FDE) is considered as a promising equalization technique for the single-carrier (SC) transmission in the next generation broadband wireless systems. However, the presence of timing offset between a transmitter and a receiver produces the inter-symbol interference (ISI) and degrades the bit error rate (BER) performance as the roll-off factor of the Nyquist filter increases. In our previous paper, we clarified the mechanism that causes the BER degradation due to the timing offset and proposed an oversampling MMSE-FDE with spectrum combining which can eliminate the negative effect of timing offset. However, since the MMSE-FDE is carried out before spectrum combining, the channel frequency-selectivity cannot be fully exploited. In this paper, we propose joint MMSE-FDE & spectrum combining which can achieve larger frequency diversity gain while suppressing the negative effect of timing offset for the SC transmission. |
