Ill-Conditioned
Linear IC detectors for low to medium SNR ill conditioned communication systems with unknown noise variance
... Many linear interference cancellation schemes have been shown to be equivalent to certain iterative methods [1], and therefore, they tend to have the same semi- convergence behavior for ill-conditioned ...
