摘要

Described herein are technologies related to an implementation of de-sensitization estimation in a receiver of a portable device.

主权项

1. A method of de-sensitization estimation comprising:
configuring an uplink transmission of a first module to a desired level; filtering of an out-of-band noise by the first module, wherein the filtering generates a residual out-of-band noise from the first module; receiving a radio frequency (RF) signal and the residual out-of-band noise by a second module during the uplink transmission; converting the RF signal into a digital RF signal by the second module; estimating a total distortion in the digital RF signal by the second module, the total distortion comprising the residual out-of-band noise and harmonic spurs due to co-running of the first and second modules; and performing correction of the digital RF signal by the second module to cancel the estimated total distortion wherein the first module is a cellular module and wherein the second module is a Wi-Fi module or a Bluetooth (BT) module.
