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 robust mathematical background in linear algebra
* Experience in developing and implementing wireless communications systems in
at least one of the following areas:
1. Array signal processing such as beam-forming and MIMO techniques for an OFDM
system
2. Physical/MAC/baseband layer software implementation for LTE/5G.
3. Adaptive equalization, receiver synchronization, signal identification and
recovery
4. Experience with OFDM based system implement
