The Role:
As a DSP Engineer working in the Digital RF Systems team, you will be responsible for DSP architecture definition, design and simulation of DSP blocks in wireless communication SOC that are used in Leo phased array systems. You will be implementing end-to-end system models including fixed point DSP blocks, RF impairments of the radio, phased array antenna and satellite channel. You will be involved in novel techniques to estimate and correct RF impairments that will be implemented in HW and FW. Based on the system level constraints such as low power and cost, you will develop optimized solutions to support high throughput for our customers.
As a DSP Engineer, you will engage with an experienced cross-disciplinary staff to conceive and design innovative product solutions. You will work closely with internal inter-disciplinary teams such as ASIC/RFIC designers, FW/SW engineers, design verification engineers. You will drive key aspects of the silicon design, validation and RF performance optimization in the lab.
In this role you will:
. Collaborate with RFIC/analog designers, communication systems and software engineers to drive chip specifications
. Develop and optimize HW/SW calibration methods for RF SOC and phased array systems
. Architect HW and FW partitioning of calibration algorithms
. Develop detailed test plans and test procedures for validation and characterization of RF Wireless SOC performance
. Involve in chip bring-up in the lab and optimize conducted and/or OTA throughput performances by collaboratively working with cross functional teams
. Characterize and enhance RF performance of the wireless SOC and help integration of the silicon into Leo phased array systems
