Abstract

A novel reduced complexity trellis-based equaliser, referred to as the In-phase/Quadrature-phase Equaliser (I/Q-EQ), is proposed. The I/Q-EQ is employed in the context of turbo equalisation (TEQ-IQ) and with the aid of iterative channel estimation. The performance of the TEQ-IQ is characterized in a noise limited environment over an equally-weighted, symbol-spaced three-path Rayleigh fading channel. The TEQ-IQ achieved the same performance as the conventional turbo equaliser, while achieving a complexity reduction by a factor of 1.25 and 7.17 for 4-QAM and 16-QAM, respectively.
