You will be working on the design, development, and integration of calibration software modules for wireless communication systems using multiple antennas.
Design, development, integration, and testing calibration software modules for a next-generation fixed wireless broadband system. The primary focus is functionality in layer 1 of the proprietary 5G protocol, such as channel estimation, IQ imbalance correction, and LO leakage cancellation.
You will develop software running on both the base station and user equipment of a broadband wireless access system for various multicore DSP/ARM processors and real-time operating systems. You will collaborate closely with L2/L3 software groups and FPGA/ASIC teams to deliver cross-layer features.
Job Responsibilities:
- Design and develop scalable PHY/Calibration software modules on multi-core DSP/GPP using C/C++
- Define and develop unit test vectors using Matlab and C++ for the software modules and unit test extensively to deliver flawless modules
- Test and validate the performance of the software modules on the real system.
- Develop scripts to qualify the RF board testing
Required Skills & Experience:
- MS or PhD in Electrical Engineering/Computer Science with an emphasis in wireless communication and/or digital signal processing
- 5-12 years of industry experience in DSP software development for wireless communication systems (such as 5G, LTE, WiFi, or similar proprietary protocols)
- Formal understanding in communication and signal processing theory and techniques, with solid mathematical background in linear algebra
- Experience in developing and implementing wireless communications systems in at least one of the following areas:
- Array signal processing such as beam-forming and MIMO techniques for an OFDM system
- Physical/MAC/baseband layer software implementation for LTE/5G.
- Adaptive equalization, receiver synchronization, signal identification and recovery
- Experience with OFDM based system implementation
- Ex
