ABSTRACT
Low complexity equalization of doubly selective channels is motivated for real time processing of received signals to establish duplex communications. Bi-directional equalization can improve the bit error rate performance. Bi-directional equalizer performs two equalizations, one on received block of information and other on its time reversed version. This can result in an increased complexity. The time varying nature of the doubly selective channel is also a cause for concern, from the perspective of computational complexity. Several low complexity equalization techniques for doubly selective channels have been reported in the literature. This work studies low complexity bi-directional equalization of doubly selective channels. The proposed scheme of bi-directional equalization offers low computational complexity in comparison with existing low complexity approaches of equalization of doubly dispersive channel.
