With an impressive portfolio of 10 patents, he has made significant strides in addressing challenges associated with radio frequency impairments in communication systems.
Latest Patents
Among his latest patents, Vijay's work on "Over the air acquisition of radio frequency impairment information" is particularly noteworthy. This patent introduces systems and methods for providing indications about TX RF non-linear impairments. In various implementations, a first device, either a User Equipment (UE) or a base station, estimates Error Vector Magnitude (EVM) indications for a transmitted signal and detects whether the EVM exceeds a predetermined threshold. When this threshold is surpassed, the first device may communicate the estimated TX non-linearity indications, including metrics such as AM-AM and AM-PM, to a second device that transmitted the signal. Furthermore, the patent details systems for wireless communication impairment correction, wherein the first device utilizes the estimated indications to perform non-linear correction on a transmit signal for the corresponding receiver device.
