  • Mixed signal dynamical environment modeling
    Patent number: 6859772
    Abstract: A device (2) and method (20) for providing a balanced parameterized description of a dynamical environment having a plurality of signal sources. The method (20) includes inverse transforming (25) an initial reduced cost set of discrete time parameters into a reduced cost set of continuous time parameters and then converting (26) the reduced cost set of continuous time parameters into a balanced converted set of parameters. A transforming step (26) for transforming the balanced converted set of parameters into a modified set of discrete time parameters is then effected and thereafter an estimating step (28) estimates from the modified set of discrete time parameters a balanced reduced cost set of discrete time parameters. Steps (25) to (28) are repeated until the balanced reduced cost set of discrete time parameters provides a rate of change value of a cost function that reaches a pre-determined value.
