Jhw. Penm et al., A NOTE ON THE SEQUENTIAL FITTING OF MULTICHANNEL SUBSET AUTOREGRESSIONS USING THE PREWINDOWED CASE, IEEE transactions on signal processing, 43(1), 1995, pp. 322-327
In this correspondence, an efficient adaptive algorithm for multichann
el subset autoregression identification using the prewindowed case is
developed. After the initialization is carried out by the direct metho
d. the optimum multichannel subset autoregression at each time instant
is selected by employing the proposed recursions in conjunction with
a model selection criterion.
