Abstract:

IB-DFE (Iterative Block DFE) is a promising turbo equalization technique for SC-FDE schemes (Single-Carrier with Frequency Domain Equalization). However, typical IB-DFE implementations are tailored for a specific constellation (usually QPSK). In this paper we propose a general method for designing IB-DFE receivers for any constellation. Our approach relies on an analytical characterization of the mapping rule were the constellation symbols are written as a linear function of the transmitted bits. This method is then employed in both uniform and non-uniform QAM constellations.
