Key Qualifications：
We are looking for candidates with in-depth knowledge on wireless communication system (OFDM/MIMO, etc.)
A background in 3GPP standardization in RAN1 or RAN4 is a significant plus.
Deep understanding of communication theory & signal processing related algorithms design (such as timing recovery, signal estimation and detection, automatic gain control, RF impairment estimation and correction, channel estimation, equalization, coding theory, etc.)
Experience with Matlab or Python and/or C/C++ for algorithm development, modeling, and simulation.
Education & Experience：
BS and 10 + years of relevant experience.
招聘部门：
Apple Hardware
工作地点：
Beijing, Beijing, China
面试建议：
Apple正在寻找一位能够参与3GPP标准制定并推动创新调制解调器开发的RAN标准工程师。这个职位最核心的要求是深入理解无线通信系统设计和3GPP标准化流程，特别是RAN1和RAN4相关经验。面试官会特别关注你在5G物理层算法开发和系统模拟方面的实际经验。 准备这个面试时，你需要重点展示你在3GPP标准化工作中的具体贡献，特别是任何直接影响标准制定的技术提案。准备好详细讨论你参与的无线通信系统设计项目，特别是涉及OFDM/MIMO技术的案例。由于工作需要大量算法模拟，建议准备几个用Matlab/Python/C++实现的算法开发实例，能够清晰解释你的设计思路和性能优化方法。同时，考虑到这个职位需要参与国际标准会议，你的英语沟通能力和技术表达能力也会是考察重点。
