University of San Diego

What you'll study

A research doctorate in communications engineering focuses on advancing theory and practice in signal processing, wireless and optical communications, networked systems and electronic device technologies. Coursework in the early stages typically covers advanced probability and stochastic processes, estimation and detection theory, information theory, modern digital communication systems, antenna and RF theory, and advanced signal processing (including adaptive and statistical methods).

After a period of taught modules and qualifying examinations, the programme centres on independent research leading to a doctoral dissertation. Research areas commonly pursued include wireless communications and 5G/6G architectures, millimetre-wave and terahertz systems, massive MIMO, network information theory, machine learning for communications, error-control coding, optical communications and photonics, software-defined radio, sensor networks and Internet of Things communications, and hardware/analog-digital co-design.

Training emphasises a mix of theory, simulation and laboratory experimentation. Doctoral candidates typically engage in:

• Advanced seminars and reading courses in specialised topics
• Laboratory and prototyping work using SDRs, RF testbeds, photonic benches or ASIC/FPGA platforms
• Collaborative projects with industry partners and multidisciplinary research groups
• Teaching or mentoring undergraduate laboratory courses
• Scholarly dissemination through conference presentations and journal publications

Entry requirements

Competitive applicants normally hold a relevant master’s degree (or equivalent) in electrical engineering, computer engineering, applied physics or a closely related field. Strong applicants without a master’s degree typically present an excellent bachelor’s record alongside substantial research experience.

• Academic record: A strong transcript in core subjects such as circuits, electromagnetics, signals and systems, communications and probability/statistics.
• Research experience: Evidence of research potential such as a master’s thesis, publications, technical reports or significant project work.
• References: At least two or three academic references that can speak to research aptitude and potential for doctoral study.
• Statement of purpose: A clear research statement outlining interests, prior projects and proposed areas of dissertation research.
• English language proficiency: For applicants whose first language is not English, an accepted English test or equivalent proof of proficiency is normally required.

Additional application elements may include a curriculum vitae, sample publications or reports, and an interview with potential supervisors. Specific formal prerequisites and application procedures should be checked with the University of San Diego admissions office or the relevant engineering school.

Career prospects

Graduates with a PhD in communications engineering pursue careers across academia, industry and public sector research. Typical pathways include:

• Academic careers: Postdoctoral research and faculty positions in universities and research institutions, focusing on teaching and continued research.
• Industry R&D: Senior research scientist or engineering roles in telecommunications, semiconductor companies, aerospace and defence contractors, and technology firms developing wireless and optical systems.
• Systems and network architects: Designing large-scale communication networks, cloud-native communications platforms and next-generation wireless infrastructure.
• Start-ups and entrepreneurship: Founding or joining early-stage companies commercialising novel RF, photonics or signal-processing technologies.
• Standards and policy roles: Technical leadership in standards bodies, regulatory agencies or non-profit organisations that shape communications policy and interoperability.

Doctoral training also prepares graduates for technical leadership and management roles that require strong analytical skills, research literacy and the ability to translate innovation into deployed systems.

Why study at University of San Diego

The University of San Diego’s engineering school emphasises small-class engagement, interdisciplinary collaboration and connections to the San Diego technology ecosystem. The region is a hub for wireless communications, defence electronics, satellite and photonics firms, which creates opportunities for applied research collaborations, internships and industry-funded projects.

Within USD, students benefit from hands-on laboratory facilities, opportunities to work with faculty on applied research problems, and a focus on ethical, socially responsible engineering aligned with the university’s mission. Doctoral candidates can often pursue interdisciplinary partnerships across departments—for example, working with computer science, mechanical engineering, and health sciences researchers on sensing and communications challenges—and may leverage local industry and government laboratories for translational research and prototyping.

Prospective students should contact the Shiley-Marcos School of Engineering (or the relevant faculty group) to confirm current doctoral offerings, available supervisors, and specific admission procedures for advanced research degrees in communications engineering.
