Bounds for the mixing parameter within the CC-CMA algorithm applied in non ideal multiuser environments Yuhui Luo Jonathon Chambers 2134/5822 https://repository.lboro.ac.uk/articles/conference_contribution/Bounds_for_the_mixing_parameter_within_the_CC-CMA_algorithm_applied_in_non_ideal_multiuser_environments/9556583 We derive new bounds for the mixing parameter, γ, within the cross-correlation constant modulus algorithm (CC-CMA) for blind source separation and equalization in non-ideal multiuser environments. Channel undermodelling and noise are considered when the complex sources are circularly symmetric. These tighter bounds are obtained by surface topography of the error performance surface of the CC-CMA algorithm, and replace earlier work which suggested that γ>4/3. The validity of the bounds is confirmed by simulation studies 2010-01-18 15:01:43 Blind equalisers Correlation methods Multiuser channels Parameter estimation Signal detection Mechanical Engineering not elsewhere classified
