Abstract: A multi-mode wireless communications device ( 100 ) and methods therefor, including a first transceiver having a continuous reception mode receiver coupled to a first antenna ( 138 ) and a second transceiver having a second transmitter coupled to a second antenna ( 140 ). In one mode of operation, the continuous reception mode receiver receives an uncompressed downlink signal at the same time the other receiver receives a signal. In another mode of operation, the continuous reception mode receiver receives an uncompressed downlink signal at the same time a transmitter of the second transceiver transmits a signal. In another mode of operation, a continuous reception mode transmitter of the first transceiver transmits an uplink signal at the same time the other receiver receives a signal.

Abstract: A method to reduce crossmodulation in a multimode radio communication device with a transmitter, a receiver, and a second receiver (400) that operates in a receiver channel bandwidth (402) includes a step of measuring a first signal strength in the receiver channel bandwidth (404), a second signal strength outside of the receiver channel bandwidth (406), and a power level of the transmitter. A next step (408) includes determining a signal-to-crossmodulation interference ratio (SCMIR). A next step (410) includes calculating a SCMIR threshold. A next step (412) includes comparing the ratio to the threshold. A next step (416,420) includes increasing the linearity of the receiver if the ratio is less than the threshold.
Abstract translation: 一种减少在具有在接收机信道带宽（402）中操作的发射机，接收机和第二接收机（400）的多模式无线电通信设备中的交叉调制的方法包括测量接收机信道带宽中的第一信号强度 404），在接收机信道带宽（406）之外的第二信号强度，以及发射机的功率电平。 下一步骤（408）包括确定信号到交叉调制干扰比（SCMIR）。 下一步骤（410）包括计算SCMIR阈值。 下一步骤（412）包括将该比率与阈值进行比较。 下一步骤（416,420）包括如果比率小于阈值则增加接收机的线性度。

CPC classification number: H04B1/406 , H04B1/1027
Abstract: A multimode wireless receiver circuit (10) includes multi-receiver control and interference detection logic (50) and least two separate receivers: a first receiver (20) associated with a first radio access technology and a second receiver (30) associated with a second radio access technology. The multi-receiver control and interference detection logic (50) simultaneously controls the second receiver (30) to detect an interference blocker signal (100), while the first receiver (20) receives at least a portion of the wireless signal (80) and the interference product signal (90). In response to the second receiver (30) detecting the interference blocker signal (100), the multi-receiver control and interference detection logic (50) adjusts at least one operating condition of the first receiver (20) such that the interference product signal (90) received by the first receiver (20) is reduced.
