Wireless repeater with arbitrary programmable selectivity
View Patent ↗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.
1. 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.
2. The system of claim 1 wherein the repeater includes a Hilbert filter facility.
3. The system of claim 1 wherein the repeater includes an image noise filter.
4. The system of claim 1 wherein the repeater includes a simplified frequency architecture.
5. The system of claim 4 wherein the simplified frequency architecture includes a high reference oscillator frequency.
6. 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.
7. The system of claim 6 wherein the adaptive cancellation includes an adaptively weighted transmission sample.
8. The system of claim 6 further comprising providing a user interface adapted to select at least one sub-band.
9. The system of claim 6 wherein the repeater includes a Hilbert filter facility.
10. The system of claim 6 wherein the repeater includes an image noise filter.
11. The system of claim 6 wherein the repeater includes a simplified frequency architecture.
12. The system of claim 11 wherein the simplified frequency architecture includes a high reference oscillator frequency.
