Embodiment Construction

[0011] Described herein are techniques for increasing inverse sensitivity in a receiver circuit or system of a portable device. For example, such as during a downlink (LD) data communication operation via a first modem (eg, a cellular / LTE modem) the operating frequency is subjected to radio frequency (RF) interference from a second modem (eg, Wi-Fi, BT, etc.) ) signal, and vice versa. In this example, when the second modem is an aggressor modem, the RF signal from the second modem may provide out-of-band overload current or interference to at least one antenna of the first modem. As such, a calibration process may be performed to remove these effects on the at least one antenna of the first modem.

[0012] In an implementation, the first modem is configured to receive a first set of radio frequency (RF) signals (eg, a set of calibration RF signals) from a second modem during DL data communication or during a discontinuous reception (DRx) mode. In this implementation, the fir...

Abstract

This application concerns cellular uplink harmonic spurious suppression in Wi‑Fi and Bluetooth receivers. In particular, it relates to a method and device receiver for increasing inverse sensitivity in a receiver circuit of a device. The method includes: performing data communication by at least one antenna of a first modem; receiving a first set of radio frequency RF signals from a second modem during the data communication; determining the contribution of the first set of RF signals to the data communication currently performed in the first modem Influence; determining a beamforming vector based on the determined influence of the first set of RF signals, wherein a second set of RF signals uses the determined beamforming vector; and receiving the second set of RF signals.

Description

technical field [0001] The present disclosure relates generally to wireless communication systems and, more particularly, to cellular uplink harmonic spur suppression in Wi-Fi and Bluetooth receivers. Background technique [0002] A wireless communication system may use one or more channels to transmit data between a transmitter and a receiver. These communication systems may operate according to a set of standards defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 for wireless local area networks (WLANs). [0003] During the transmission of data between the transmitter and receiver, multipath issues and other conditions such as the presence of interfering signals may affect the reception of data packets. For example, the presence of harmonic spurs that may intermingle with the reception of data packets can cause problems for signal detection, amplifier gain adjustment, and signal decoding. To this end, wireless communication systems employ vari...
