Abstract
Apparatuses, methods and systems of selecting a gain setting of a receiver chain are disclosed. One method includes bypassing a filter portion of the receiver chain and sampling a bypass receive signal while the filter portion of the receiver chain is bypassed. If the sampled bypass receive signal is determined to be saturated greater than a threshold, then selecting a gain setting of the receive chain as a function of the saturation. Further, the filter portion of the receive chain is included while sampling a receive signal with the selected gain setting.
Claims25
A method of selecting a gain setting of a receiver chain, comprising:
- bypassing a filter portion of the receiver chain;
- sampling a bypass receive signal while the filter portion of the receiver chain is bypassed;
- if the sampled bypass receive signal is determined to be saturated greater than a threshold, then selecting a gain setting of the receive chain as a function of the saturation;
- and
- including the filter portion of the receive chain and sampling a receive signal with the selected gain setting.
A receiver, comprising:
- a receiver chain, the receiver chain comprising;
- a filter portion;
- a receiver sampler;
- a controller operative to control bypassing of the filter portion, and receiving samples of the receiver sampler, wherein if a sampled receive signal while the filter portion is bypassed is determined to be saturated greater than a threshold, then selecting a gain setting of the receive chain as a function of the saturation;
- the controller further operative to including the filter portion of the receive chain and set receiver chain to the selected gain setting for receiving a receive signal.
