Abstract
Described herein are technologies related to an implementation of de-sensitization estimation in a receiver of a portable device.
Claims18
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.

A device receiver comprising:
- a first module configured to transmit a signal to a desired level, wherein the signal undergoes an out-of-band noise filtering to generate a residual out-of-band noise from the first module;
- a second module configured to receive a radio frequency (RF) signal and the residual out-of-band noise during the transmission of the signal by the first module, the second module further comprises:
- an analog-to-digital converter (ADC) that converts the received RF signal into a digital RF signal;
- a digital noise estimator configured to estimate a total distortion in the digital RF signal, the total distortion includes the residual out-of-band noise from the first module and harmonic spurs due to co-running of the first and second modules;
- a memory to store the estimated total distortion;
- and
- a processor configured to perform a corrective algorithm 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.
4 more elements
One or more non-transitory computer-readable media storing processor-executable instructions that when executed cause one or more processors to perform operations comprising:
- configuring a first module to transmit a signal 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 of a radio frequency (RF) signal and the residual out-of-band noise by a second module during the transmission of the signal;
- 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, wherein the total distortion includes at least the residual out-of-band noise from the first module;
- and
- performing a correction by the second module to mitigate effects of the estimated total distortion wherein the first module is a cellular module while the second module is a Wi-Fi module or a Bluetooth (BT) module.
