SELECTIVE POWER REDUCTION TO MITIGATE BAND INTERFERENCE

摘要

A method includes transmitting a first set of transmission signals over an operating frequency band. The method includes detecting if a second set of transmission signals are transmitted adjacent the operating frequency band and reducing power to a subset of the first set of transmission signals when the second set of transmission signals are detected.

1. A device comprising:
A. an antennae; B. a transmitter having a data input, a power control input, and an output coupled to the antennae, the transmitter generating operating transmission signals over an operating frequency band in response to data signals on the data input and at varying power levels in response to power signals on the power input; C. detector circuitry having an antennae receiving any transmission signals adjacent the operating frequency band and a detector output carrying a detector signal indicating whether any transmission signals adjacent the operating frequency band are received; and D. a processor having a detector input coupled to the detector output, a data output coupled to the data input, and a power output coupled to the power input, the processor issuing a varying power control signal on the power output in response to the detector signal.
