Bandwidth efficient single carrier systems with frequency domain equalisation

Abstract

A new bandwidth efficient single carrier system with frequency domain equalisation is proposed. Turbo equalisation and cyclic prefix reconstruction are combined together to eliminate the normally required cyclic prefix for such a system. The proposed method achieves much better performance than the residual inter-symbol interference cancellation approach by utilising soft decoded information and introducing turbo equalisation. The performance of the proposed scheme is studied through simulations.
