ABRLS algorithm for time variant channel equalisation

This paper proposes a non-linear adaptive algorithm, the ABRLS algorithm, as an adaptation procedure for time variant channel equalisers. In the ABRLS algorithm, a coefficient matrix is updated based on the amplitude level of the received sequence. To enhance the tracking capability of the ABRLS algorithm, a parallel adaptation scheme is deployed which involves the structures of decision feedback equaliser(DFE). Computer simulations demonstrate that the novel ABRLS DFE provides a significant improvement related to the conventional RLS DFE on rapidly time variant communication channels.
