Patent number: 11985012Abstract: The embodiments described herein are directed at techniques to de-correlate Bluetooth interference seen across WLAN receive antennas/space in a Bluetooth transceiver/WLAN transceiver combination device. A Bluetooth interference whitening technique may be utilized, wherein a whitening matrix is computed based on a leakage signal resulting from a training signal transmitted by the Bluetooth transceiver. The leakage signal may leak in to the WLAN transceiver and a set of attributes is calculated for each frequency the leakage signal is received on. One or more whitening matrixes are calculated based on the set of attributes for each frequency the leakage signal is received on. In response to the WLAN transceiver receiving a signal of interest, an appropriate whitening matrix from the one or more whitening matrixes is selected and is then applied to the received signal of interest to de-correlate any interference generated as a result of the Bluetooth transmission.Type: GrantFiled: October 5, 2022Date of Patent: May 14, 2024Assignee: Cypress Semiconductor CorporationInventors: Ankit Sharma, Suprojit Mukherjee, Ayush Sood, Ashok Nimmala

Patent number: 11272382Abstract: Systems, methods, and devices reduce interference experienced by wireless communications devices. Methods include receiving a first signal from a first transceiver, the first signal being compatible with a first communications protocol, and configuring a filter based, at least in part, on the received first signal, the filter being communicatively coupled to a second transceiver collocated in a same wireless communications device as the first transceiver. The methods further include receiving a second signal, the second signal being compatible with a second communications protocol, and filtering the second signal to remove at least some components of the first signal from the second signal, the filtering reducing at least some interference from the first signal with the second signal. The methods also include providing the filtered second signal to the second transceiver.Type: GrantFiled: March 26, 2020Date of Patent: March 8, 2022Assignee: Cypress Semiconductor CorporationInventors: Ankit Sharma, Ayush Sood, Suprojit Mukherjee, Ashok Nimmala, Rajendra Kumar Gundu Rao
