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.
Claims20
A repeater system configured for sampling, filtering, and repeating an RF signal, the system, comprising:
- a digital signal processor (DSP) configured to receive the RF signal;
- and
- a multi-sub bandpass filter configured to
- receive and process sub bands with a plurality of tap weight coefficients,
- use a coefficient of the tap weight coefficients to process a sub band of the sub bands at one or more time-shifted stages;
- and
- use the one or more time-shifted stages to define a count indicative of a number of stages in the one or more time-shifted stages that is independent of a count descriptive of a number of the sub bands being processed concurrently by the multi-sub bandpass filter.

A method of sampling, filtering, and repeating an RF signal including a plurality of sub bands, comprising:
- receiving, by a digital signal processor (DSP), the RF signal;
- receiving and processing, by a multi-sub bandpass filter, the sub bands with a plurality of tap weight coefficients;
- concurrently processing, by the multi-sub bandpass filter, the sub bands;
- processing, by the multi-sub bandpass filter, a sub band of the sub bands at each of a plurality of time-shifted stages using a coefficient of the tap weight coefficients;
- wherein the plurality of time-shifted stages define a count, the count being indicative of a number of stages in the plurality of time-shifted stages that is independent of a count descriptive of a number of sub bands being processed by the multi-sub bandpass filter.
