Patent number: 10742314Abstract: Disclosed herein, one embodiment of the disclosure is directed to a system, apparatus, and method for enabling simultaneous transmit and receive in the same Wi-Fi band within a device by first obtaining a first information corresponding to a first set of signals to be transmitted wirelessly by a first antenna of a first device and transmitting, by the first antenna of the first device, the first set of signals. Then, a second set of signals comprising: (a) the first set of signals transmitted by the first antenna of the first device and (b) a third set of signals transmitted by a second device different than the first device are received by a second antenna of the first device. Thereafter, a second information representing the second set of signals received by the second antenna of the first device is obtained. Last, based on the first information and the second information, a third information comprising an estimation of the third set of signals without the first set of signals is determined.Type: GrantFiled: March 22, 2018Date of Patent: August 11, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Ahmed Khidre, Deven Mohan Patel, Farhan Hasnain, Prakash Guda
