Abstract
The invention relates to wireless repeater systems and methods. In embodiments, such systems and methods involve receiving a wireless transmission signal; and processing the wireless transmission signal using a digital signal processing facility (DSP); wherein the DSP is adapted to filter at least one sub-band of the wireless transmission signal using a digital bandpass filter.
Claims17
A system, comprising:
- a wireless transmission signal repeater;
- wherein the wireless transmission signal repeater is adapted to process a received signal through a digital signal processor (DSP) using a composite multi-sub-bandpass filter.
A system, comprising:
- a wireless transmission signal repeater;
- wherein the wireless transmission signal repeater is adapted to process a received signal through a digital signal processor (DSP) using a composite multi-sub-band bandpass filter and including adaptive cancellation of a transmitter wrap-around leakage.
The method, comprising:
- providing a cell phone transmission signal repeater that includes a multi-sub-band bandpass filter for filtering a plurality of sub-bands of a composite multi-band signal;
- taking a plurality of sets of filter coefficients wherein each set of filter coefficients represents one sub-band of the composite multi-band signal;
- summing at least a portion of the plurality of sets of filter coefficients to form a composite set of filter tap weights;
- and
- filtering the composite multi-band signal with the multi-sub-band bandpass filter using the composite set of filter tap weights.
