Abstract

Although space-time blind equalization algorithms have been widely studied in the last decade, their convergence and tracking behavior are not yet completely characterized. In this paper, we address the tracking analysis of space-time blind quasi-Newton algorithms, using the energy conservation relation. We obtain an expression to adjust the algorithms to reach the same steady-state mean-square error. Assuming a low degree of nonstationarity and high signal-to-noise ratio, close agreement between analytical and simulation results is observed.
