摘要

Broadly speaking, the embodiments disclosed herein describe an apparatus, system, and method for managing the effects of TDMA noise emitted by a communication device on an audio circuit.

主权项

1. A method performed by a portable communication device that is time division multiple access (TDMA) enabled, the method comprising:
determining whether the portable communication device is in a connected state with a wireless network; activating a TDMA noise management mode in response to determining that the portable communication device is in the connected state with the wireless network; while the TDMA noise management mode is activated:
generating a TDMA noise modification signal associated with a TDMA noise signal emitted by the portable communication device, the TDMA noise modification signal configured to reduce an electromagnetic coupling between the TDMA noise signal and an audio circuit that is external to the portable communication device, andbroadcasting the TDMA noise modification signal separately from emission of the TDMA noise signal; and suspending the TDMA noise management mode during a period of data inactivity between the portable communication device and the wireless network.
