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 cell phone transmission signal repeater;
wherein the cell phone transmission signal repeater is adapted to process a received signal through a digital signal processor (DSP) using a composite multi-band bandpass filter and wherein the cell phone transmission signal repeater includes a low-spurious up-conversion facility.
2. The system of claim 1 wherein the cell phone transmission signal repeater is a bi-directional repeater.
3. The system of claim 1 wherein the DSP further comprises a bandpass filter; wherein the bandpass filter is a programmable arbitrary filter.
4. The system of claim 1 wherein the DSP includes a simplified frequency architecture.
5. The system of claim 4 wherein the simplified frequency architecture includes a high reference oscillator frequency.
6. The system of claim 1 wherein the cell phone transmission signal repeater performs differential processing.
