| Abstract(in English) | The symbol-rate sampling frequency-domain equalization (FDE) is considered 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 work, we clarified the mechanism that causes the BER degradation due to the timing offset and proposed a joint MMSE-FDE & spectrum combining that can achieve larger frequency diversity gain while suppressing the negative effect of timing offset. In this paper, we evaluate the impact of time-multiplexed pilot-assisted channel estimation (PACE) on the SC transmission using the proposed joint MMSE-FDE & spectrum combining in the presence of timing offset. |
