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. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the configuring of the uplink transmission includes setting one or more stages of an amplifier in the first module to a desired level, wherein the out-of-band noise is produced by the one or more stages of the amplifier. ### Claim 3 (depends on 2) The method as recited in claim 2, wherein the estimating of the total distortion is based at least upon the out-of-band noise that is received by the second module. ### Claim 4 (depends on 1) The method as recited in claim 1, wherein the configuring of the uplink transmission includes configuring a filter to reject the out-of-band noise in the first module, wherein the filtering of the out-of-band noise rejection creates an additional distortion. ### Claim 5 (depends on 4) The method as recited in claim 4, wherein the estimating of the total distortion is based at least upon the additional distortion created by the filtering of the out-of-band noise. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein the estimating of the total distortion is based at least upon an antenna isolation between a first antenna of the first module and a second antenna of the second module. ### Claim 7 (depends on 1) The method as recited in claim 1, wherein the digital RF signal includes a receiver filter insertion loss due to components of the second module. ### Claim 8 (depends on 7) The method as recited in claim 7, wherein the estimating of the total distortion is based at least upon the receiver filter insertion loss. ### Claim 9 (depends on 1) The method as recited in claim 1, wherein the digital RF signal includes receiver in-channel blocking effects. ### Claim 10 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 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. ### Claim 11 (depends on 10) The device receiver as recited in claim 10, wherein the first module further comprises one or more stages of an amplifier that produces the out-of-band noise. ### Claim 12 (depends on 11) The device receiver as recited in claim 11, wherein the digital noise estimator is configured to estimate the total distortion based at least upon the residual out-of-band noise included in the received digital RF signal. ### Claim 13 (depends on 10) The device receiver as recited in claim 10, wherein the first module further comprises a filter to reject the out-of-band noise in the first module, wherein the filtered out-of-band noise creates an additional distortion in the second module. ### Claim 14 (depends on 13) The device receiver as recited in claim 13, wherein the digital to noise estimator is configured to estimate the total distortion based at least upon the additional distortion created by filtering the out-of-band noise rejection on the first module. ### Claim 15 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;
