This selection is based upon the intermodulation product's amplitude.
Next, the intermodulation product's amplitude is compared to a predetermined threshold.
A divider receives the cross-covariance value, the auto- covariance value and the second order intermodulation product correction factor and generates a running average second order intermodulation product correction factor.
The error signal represents a subset of the intermodulation products, where an intermodulation product of the subset corresponds to the unacceptable frequency range.
A buffer system stores a second order intermodulation product correction factor.
A dot product is also determined for the received signal.
A cross product is determined for a received signal.
If the cross product is greater than a predetermined threshold, the cross product is decremented by the product of the dot product multiplied by a constant value.
If the cross product is greater than or equal to the predetermined threshold, the cross product is incremented by the product of the dot product multiplied by the constant value.
The cross product bus couples the first intelligent electronic device to the transferable intelligent control device.
Such an ideal multiplier can be used as a mixer with low local oscillator power requirement and virtually no inter-modulation products.
third order RIM product
In one embodiment, the invention further includes a window function suitable for use with block-based cross-product enhanced HFR.
An integrated intelligent system includes a first intelligent electronic device, a second intelligent electronic device, a transferable intelligent control device (TICD) and a cross product bus.
For this purpose, two signals of different frequency (14, 22) are introduced into the signal transmission path and a time span until an intermodulation product (32) arrives at the introduction point (28) of the two signals is measured.
The local oscillator frequency is arranged to place a third order intermodulation product having a frequency equal to the local oscillator frequency minus three times the modulation frequency within the assigned channel bandwidth.
