DIGITAL ADAPTATION INTERFERENCE CANCELLATION REPEATER

A digital adaptive interference removing repeater is provided to process weight operation with only a code of a reference signal when weight is operated, thereby reducing multipliers within a coefficient update unit and decreasing overall digital circuit logic.

Beschreibung
Zusammenfassung:	A digital adaptive interference removing repeater is provided to process weight operation with only a code of a reference signal when weight is operated, thereby reducing multipliers within a coefficient update unit and decreasing overall digital circuit logic. A multiplier(333a) outputs values which multiply a step size by an error signal. Plural weight calculators(333b) output weight by applying a signed bit value of a reference signal to the values outputted from the multiplier. Coefficient calculators(333c) calculate a filter coefficient by adding weight individually outputted from the plural weight calculators to a previous filter coefficient. The weight calculators are adders.
