Abstract :
Equalization based on blind channel estimation using the second-order statistics has a rapid convergence rate and is potentially attractive in digital wireless communications. The asymptotic behavior of this type of approach is investigated. In particular, the achievable lower bounds of the asymptotic mean-square error (MSE) are derived to serve as benchmarks for a class of blind equalization algorithms using second-order statistics. It is shown that the convergence rate of these equalizers suffers when channels are ill-conditioned. Applying this analysis to systems using antenna arrays, the performance gain of multiple receivers over single receiver is evaluated analytically
