Worked on the power control calibration for control channel perspective. System Integration of PUCCH and tested with commercial UE and SMU. Worked on the 3GPP compliance verification for PUCCH
• 2) Optimization of LTE eNB PRACH signal chain on Freescale PSC913x SOC.
• 3) Developed FAPI compliant L1-L2 message flow for PUSCH on Freescale B3421 soc.
• 4) Experience in working with Freescale FAE’s and handling various customer related issues, provided solutions to their requirements in hard time line.
• 5) Worked with 3rd party vendor to integrate their L2 stack with Freescale L1.
• 6) Provided design and source code training to various Freescale customers on eNB-L1 for PUCCH and PRACH modules.
• Paper publication on PUCCH SINR algorithm in IEEE conference in ICACCS-2015
