近来，具有频域均衡的单载波传输由于具有低计算复杂度并且即使在强频率选择性信道中也能够获得优异的性能而吸引了很多关注。我们评估的性能直接序列超宽带（DS-UWB）与频域信道估计（FDCE）和均衡（FDE）在UWB多径信道，并比较它与传统的DS-UWB与时域信道估计（TDCE）和RAKE接收机。特别是，我们专注于使用FDCE和FDE的频域过程（FDP）的计算复杂度，并将其与使用TDCE和RAKE的时域过程（TDP）的计算复杂度进行比较。仿真结果表明，基于FDP的DS-UWB具有比基于TDP的DS-UWB更低的计算复杂度和更好的性能。
Recently, single-carrier transmission with frequency domain equalization has attracted much attention because of having low computational complexity and being able to obtain an excellent performance even in strong frequency selective channels. We evaluate the performance of direct sequence-ultra wideband (DS-UWB) with frequency domain channel estimation (FDCE) and equalization (FDE) in the UWB multipath channel and compare it to that of conventional DS-UWB with time domain channel estimation (TDCE) and a RAKE receiver. In particular, we focus on the computational complexity of the frequency domain process (FDP) that uses FDCE and FDE and compare it to that of the time domain process (TDP) that uses TDCE and RAKE. Our simulation results show that DS-UWB with FDP has significantly the less computational complexity and achieves a better performance than DS-UWB with TDP.
