Abstract

A novel iterative equaliser, the 2-dimensional iterative soft decision interference cancellation (ISDIC) (2D ISDIC) equaliser, is introduced. The 2D ISDIC is the first equaliser that bridges the gap between the low-complexity ISDIC equaliser which has poor performance, and the high-complexity inverse-channel equalising methods, such as the LMMSE and the MMSE ISDIC equalisers, which have better performances. The 2D ISDIC will be incorporated into the turbo equalisation scheme, resulting in an enhanced turbo equaliser, that performs better than the conventional, state of the art, linear turbo equaliser, with lower complexity and lower amount of iterations.
