摘要
Conventional frequency-domain receivers require a fixed channel within the block duration being the performance severely affected in presence of strong Doppler effects. In this paper we propose an iterative receiver for SC-FDE schemes (Single Carrier with Frequency-Domain Equalization) that is able to mitigate strong Doppler effects. This receiver can be regarded as a modified turbo equalizer, implemented in the frequency-domain, able to compensate the Doppler effects associated to different groups of multipath components while performing the equalization procedure. Our performance results show significant improvements over the turbo-FDE, even when different multipath components have substantially different Doppler effects.
