ABSTRACT:
A system for an omni digital package for reducing interference may include a passive combiner and a transmit signal canceller. The passive combiner may be configured to combine at least two input frequencies to produce a combined signal. The transmit signal canceller may be configured to determine an interference frequency based on a combination of the at least two input frequencies. The transmit signal canceller may include a tap weight determiner configured to determine a weighting coefficient associated with the interference frequency, and a cancellation function configured to perform a cancellation operation to at least partially cancel the interference frequency from the combined signal based on the weighting coefficient.
