Experience Summary:

Senior DSP Software Engineer, CDMA Group

• Drove and achieved a major milestone for CDMA2000-1X board bringing up, pilot acquisition, synchronization, paging and access channels integration on a new hardware platform using OSE RTOS, emulator, Agilent 8960 call box and various tracing tools ahead of schedule.
• Cooperatively worked with ASIC/FPGA and MCU teams to debug and fix problems encountered while integrating DSP SW.
• Implemented, unit tested and optimized a Minimum Mean Square Error (MMSE) combining algorithm for mobile receiver diversity system in DSP.
• Optimized assembly code of a CDMA2000-1X modem SW to achieve a saving of over 3 MIPS.
• Successfully integrated AFLT (location services module) in a new hardware platform.
• Implemented DMA HW drivers and interface for transferring data from peripheral to internal memory at 52 micro second rate and from internal memory to Viterbi decoding HW at a rate of 20 milli second.
• Implemented Translational Lookaside Buffer (TLB) for optimal DMA data transfer and to reduce DMA transfer bus load.
• Implemented DLL and Channel Estimator HW drivers and interfaces for a new HW.
• Ported and modified all existing 1X modem assembly code to a new DSP platform.
• Fixed assigned DSP SW errors early or on time in to support on time product launch.
• Upgraded DSP software compiler version to take advantage of the compiler's feature to optimize code space. Saved over six Kbytes.
• Acted as a team lead, participated in recruiting candidates for DSP position and mentored new hires.
