Systems and methods for enhancing probability of internal measurements in crowded environments

摘要

A communication system having self or internal calibration is disclosed. The system includes an antenna tuner, a mismatch component, a receiver, and a strength indicator. The antenna tuner is configured to mismatch an antenna according to a mismatch code. The mismatch code includes or alters antenna characteristics of the antenna. The mismatch component is configured to provide the mismatch code to the antenna tuner. The strength indicator is configured to measure a strength of the received signal.

1. A communication system having internal calibration, the system comprising:
an antenna tuner configured to alter an amount of mismatch associated with an antenna when coupled thereto in a pre-calibration mode according to a received mismatch code, wherein the mismatch code defines one or more antenna characteristics; a mismatch component configured to provide one of a plurality of available mismatch codes to the antenna tuner as the received mismatch code in response to receipt of a first control signal; a receiver coupled to the antenna tuner and configured to provide a received signal in response to receipt of an incoming signal from the antenna tuner; and a strength indicator configured to measure a strength of the received signal and output the first control signal if the measured strength exceeds a predetermined channel threshold value indicating too much interference or noise and thus a need to create a greater amount of mismatch to further reduce the interference or noise, and output a second, different control signal if the measured strength does not exceed the predetermined channel threshold value, wherein outputting the second control signal indicates that sufficient mismatch exists to isolate the receiver from the interference or noise with the provided mismatch code, and to proceed with an internal calibration procedure.
