Develop Pixel modem software

L1 SW and firmware development for 3GPP

LTE-A signal processing algorithms and improvements

PHY firmware development for 3GPP TD-SCDMA:

*As a key member of TD-SCDMA FW team, designed and Implemented channel estimation, UE measurement, frequency tracking and time tracking algorithms for Qualcomm's first generation TD-SCDMA modem

*Brought up and supported commercialization of Qualcomm's first generation modem with TD-SCDMA support: MDM 9x15

I spent two summers in research and development related to 802.11n in 2007 and 2008. During these two summers:

*Created a complete 802.11n end to end simulation platform with advanced features like STBC, transmit beamforming. This simulator is widely used for advanced WiFi research and proof of concept studies by Cisco

*Co-invented a channel estimation algorithm that enables implicit transmit beamforming and spatial multiplexing without assistance from 802.11n/ac clients equipped with multiple transmit antennas. This invention is an essential part of Cisco's ClientLink technology. "ClientLink 3.0 uses its advanced, patent pending algorithms to provide full beamforming gain, whether clients help sound out the channel or not" [http://www.cisco.com/c/en/us/products/collateral/wireless/aironet-3700-series/white-paper-c11-731150.pdf]
