Carrier phase estimation based on single-axis constant modulus cost criterion and Bussgang criteria
Azzedine Touzni,Raúl A. Casas,Thomas J. Endres,Stephen Leonard Biracree,Christopher H. Strolle,Samir Hulyalkar +5 more
TL;DR: In this article, a single-axis blind cost criterion from the Bussgang class of functions, and its stochastic gradient, is used to generate a carrier phase error used to adjust a received and demodulated signal to near baseband.
Patent
Linear prediction based initialization of a single-axis blind equalizer for VSB signals
Raúl A. Casas,Azzedine Touzni,Thomas J. Endres,Stephen Leonard Biracree,Christopher H. Strolle,Samir Hulyalkar +5 more
TL;DR: In this paper, a linear predictive filtering and error term generation based on various cost criteria is employed for adaptive equalization of complex vestigial sideband modulated signals with an equalizer with forward and feedback filters.
Patent
DC offset correction for constant modulus equalization
TL;DR: In this paper, a blind estimation of the DC offset at the receiver is used to estimate the interference in a single-axis receiver with an equalizer accounting for DC offset within the modulated signal.
