Patent number: 9496905Abstract: A receiver architecture optimizes receiver performance in the presence of interference. In various embodiments, power estimation circuits are used with variable selectivity to determine the exact nature of the interference and to optimize the performance correspondingly. The variable selectivity is achieved using stages of filtering with progressively narrower bandwidths. Also, the actual method of optimizing the receiver performance is an improvement compared to the traditional techniques in that the gain settings and the baseband filter order (stages to be used) will be optimized based on the nature of the interference as determined by the power detector measurements. For a device such as a cellular phone that operates in a dynamic and changing environment where interference is variable, embodiments advantageously provide the capability to modify the receiver's operational state depending on the interference.Type: GrantFiled: September 3, 2015Date of Patent: November 15, 2016Assignee: Spreadtrum Communications USA Inc.Inventors: David Haub, Zhigang Xu, Jarrett Malone

Patent number: 9379747Abstract: Embodiments include a novel receiver architecture to optimize receiver performance in the presence of interference. In various embodiments, the presence of interference is detected, and the relative frequency location of the interference is detected. The relative frequency location specifies whether the frequency of the interference is high side (above the desired signal, i.e., at a higher frequency) or low side (below the desired signal). The receiver is configured based on the detected interference and relative location thereof. For a device such as a cellular phone that operates in a dynamic and changing environment where interference is variable, embodiments advantageously provide the capability to modify the receiver's operational state depending on the interference.Type: GrantFiled: August 6, 2015Date of Patent: June 28, 2016Assignee: SPREADTRUM COMMUNICATIONS USA INC.Inventors: David Haub, Zhigang Xu, Jarrett Malone

Patent number: 7519390Abstract: A multi-mode wireless device having a transceiver including a multi-mode transmitter and a multi-mode receiver. The transmitter can include a multi-mode transmit baseband portion configured to support all of the transmit modes. Similarly, the receiver can include a multi-mode baseband portion that is configured to support all of the receive modes. The transmitter can also include a frequency conversion stage that can convert the output from the transmit baseband portion to the desired transmit frequency. Multiple power amplifiers in parallel, each configured to support one or more of the operating modes, can selectively amplify the transmit signals. The receiver can include multiple low noise amplifiers (LNAs) in parallel, each configured to selectively amplify the received signals of one or more of the operating modes. The output of the LNAs can be coupled to a frequency conversion stage that downconverts the received signals and provides them to the baseband portion.Type: GrantFiled: March 10, 2005Date of Patent: April 14, 2009Assignee: Spreadtrum Communications Inc.Inventors: Lawrence Jarrett Malone, Lon Christensen

Patent number: 7333830Abstract: Methods and apparatus for synchronizing Wireless Local Area Network (WLAN) communication within a multi-mode radio. A multi-mode radio can support communication with a WLAN and at least one other wireless communication system. The multiple systems can be distinct and asynchronous. Transmitting, or attempting to transmit, over a WLAN communication link can result in interference that degrades the sensitivity of a receiver in another communication system, or that interferes with a transmission in another communication system. The WLAN transmissions can be synchronized to operation in another communication system by generating a signal that can be coupled to a collision avoidance system in the WLAN transmitter. The signal can operate to cause the WLAN transmitter to reschedule the transmission to another time such that the resources of the multi-mode radio are conserved and the WLAN interference is minimized.Type: GrantFiled: February 28, 2005Date of Patent: February 19, 2008Assignee: Quorum Systems, Inc.Inventor: Lawrence Jarrett Malone
