Communication systems Viterbi detector Ungerboeck’s receiver Channel Model Orthogonalization Fil: Maggio, Gabriel Nicolás. Universidad Nacional de Córdoba; Argentina. Fil: Rodríguez, Carmen E. Universidad Nacional de Córdoba; Argentina. A new architecture for maximum likelihood sequence detection (MLSD) in nonlinear dispersive channels (NLCs) is presented, and its robustness to inaccurate channel knowledge is analyzed. This architecture is developed by considering a novel orthogonal representation of the NLC, which is exploited to develop a front-end capable of obtaining uncorrelated symbol rate samples, representing a sufficient statistic for information decoding. This front-end is a special form of space-time whitened matched filter (ST-WMF), and the MLSD obtained by using this front-end (ST-WMF-MLSD) requires simple branch metrics due to the signal whitening. The ST-WMF also allows for space-time compression of the equivalent channel, which is exploited for further complexity reduction of the ST-WMF-MLSD. Simulation results show the good trade-off in performance and complexity obtained with the ST-WMF-MLSD, even in the presence of inaccurate channel knowledge. http://43jaiio.sadio.org.ar/proceedings/AST/search.html Fil: Maggio, Gabriel Nicolás.
