On the Convergence Speed of Turbo Demodulation With Turbo Decoding [PDF]
IEEE Transactions on Signal Processing, 2012 Iterative processing is widely adopted nowadays in modern wireless receivers for advanced channel codes like turbo and LDPC codes. Extension of this principle with an additional iterative feedback loop to the demapping function has proven to provide substantial error performance gain.

Analog Slice Turbo Decoding [PDF]
2005 IEEE International Symposium on Circuits and Systems, 2005 This paper presents the design of an analog turbo decoder for DVB-RCS-like applications using a slice architecture. The constituent decoders for different frame lengths are made up of duplicated elements chosen from a small set of reduced-size MAP decoders.

Angewandte Chemie, EarlyView.1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...
