Abstract
Two-way Wireless Relaying Networks (TWRNs)
have attracted interest recently due to the substantial bandwidth
efficiency and performance they can achieve. So far, most
research has assumed perfect timing synchronization within the
network. Unfortunately, perfect synchronization is difficult (or
impossible) to achieve as a timing misalignment between the
received versions of the two-way transmitted signals will occur
at both transmission phases. In this paper, an enhanced Parallel
Interference Cancellation (PIC) detector for TWRNs employing
a Space-time block code is proposed to mitigate efficiently the
performance degradation caused by imperfect synchronization.
In addition, a change in the transmission scheme of the TWRN is
also introduced that will enable a symbol-wise decoding process
at the receiving node. Unlike the previous PIC detector, numerical
simulations show that the proposed detection scheme can achieve
performance close to that of perfect synchronization even under
severe imperfect synchronization conditions in just two iterations,
while maintaining a low-level of computational complexity.
