Machine Learning SW Development

NB-IoT L1 SW Development

System and algorithm development at Ericsson System Management for Radio Base Stations: LTE and 5G, Physical layer and RRM. Early technical system study and feature development, including simulations, setting detailed system requirements, and driving the early phase of the system development. Features including such topics as Power Efficiency, advanced antenna systems and multi-user MIMO.Development of algorithms, system and link level simulators primarily developed in Java, C++, and Matlab.

• Member of Technical Staff- See ' Member of Technical Staff' under 'ST-Ericsson'.• Code guardian- Work to secure SW stability and quality. Code reviews (through Gerrit)- Drive SW module improvements• Senior SW developer- Working in an Agile XFT team with responsibility covering the whole NS stack from L1 (physical layer) to CAS (common access stratum). Initially WCDMA but last 6 month with LTE.Development mainly using:• EVP DSP (in-house proprietary vector DSP) & ARM processors. • C++/C/EVP-C/ASM.• Matlab.• Scripting (Perl, Python, shell) • Trace32/Lauterbach• Eclipse• Repo/GIT/Gerrit.

Main responsibilities:• Member of Technical Staff- Support with expertise in WCDMA L1- Knowledge sharing, mentoring, and education.• Module Key Responsible (MKR)- See 'WCDMA L1 SW module team leader' under 'Ericsson Mobile Platforms'.• Senior SW developer- See 'Senior SW developer' under 'Ericsson Mobile Platforms'.- System design of WCDMA for the 3:nd generation of Ericsson platform architecture- Early algorithm development on EVP (in-house proprietary vector DSP). - WCDMA L1 SW development on ARM.- Initial development on MVP (virtual platform) through FPGA bring-up and debugging of early maturity level HW blocks and SW, to ASIC bring-up. - HSPA SW and algorithm development.Development mainly using:• EVP DSP (in-house vector DSP) & ARM processors. • C++/C/EVP-C/ASM. • Matlab• Scripting (Perl, Python, Tcl).• T32/Lauterbach• MVP (virtual platform)• Eclipse• ClearCase.

Main responsibilities:• WCDMA L1 SW module team leader- Work to secure SW stability and quality.- Drive SW module improvements.- Support module team members, testers, integrators, and line and project organizations with module related issues.- Member of the WCDMA L1 architecture group.- Module team cross-site cooperation and coordination. - Coordination of SW development in module team among projects. - Mentoring.• Senior SW developer- Involved in all parts of the development process.- System design of WCDMA for the 2:nd generation of Ericsson platform architecture, and some of the derivative projects.- Early HW development and bring-up. Both FPGAs and ASICs.- Implementation of WCDMA L1 SW. CEVA DSP and ARM.- Algorithm design and development (cf. Patents).- Problem solving, debugging, and error correction.- Operator testing and customer support.Development mainly using: • CEVA DSP & ARM processors. • C/ASM. • Matlab. • Scripting (Perl & Python). • Trace32/Lauterbach, • RoseRT/RSA (for documentation), • OSE. • ClearCase.

Started at the WCDMA baseband ASIC department with DSP algorithm development (TI DSP), embedded real-time programming and HW near control code. Continued with L1 SW development in what later grew into the WCDMA L1 SW department.Worked with the first WCDMA platform from the earliest design and prototyping, to product. Thus, involved in all parts of the development process, from early system design of WCDMA for the 1:st generation of Ericsson platform architecture, feasibility and pre-studies, through implementation, test, debugging, error correction, customer support and operator testing. Close cooperation with ASIC, Research and Simulation departments.Extensive lab work with FPGAs, various test instruments, signal generators, logic analyzers, TX testers etc.Development mainly using: • TI DSP ASM • C • Matlab • Scripting (mainly perl) • OSE • ClearCase.
