Title
Single Carrier Block Transmission Without Guard Interval
Abstract
This paper proposes a simple detection scheme for a single carrier block transmission (SCBT) without guard interval (GI). Although the SCBT without the GI can significantly increase bandwidth efficiency, the received signal suffers from inter- block interference (IBI) and inter-symbol interference (ISI), which cannot be effectively equalized by a frequency domain equalizer (FDE). In the proposed scheme, the IBI is cancelled by using a previously detected signal. Moreover, taking advan- tage of the temporal localization of the difference of the ISI component between the received signal with and without CP, we change the channel matrix from Toeplitz structure into a circulant matrix in order to utilize the conventional FDE. Com- puter simulation results show that the proposed scheme can outperform a linear MMSE equalizer with lower computational complexity.
