    August 1995-August 2000: FW engineer at Bosch Telekom in Pandrup, Denmark
    During the 5-year period, I have worked for Dancall Telecom, which was acquired by Bosch Telecom in 1997. Then later in 2000 Siemens Mobile Phones acquired Bosch Telecom. I worked with GSM chip-set design and development for the first 2 years until the Bosch Telecom acquisition. The following three years I have been involved with systems and baseband chip-set design for a UMTS chip-set. My main responsibilities at Dancall/Bosch/Siemens were design of receiver algorithms and specification of GSM and UMTS handsets.
    • UMTS work: I worked with algorithm, architecture, and DSP development for a chip-set development for UMTS. My areas of responsibility included:
      • Channel model development and implementation.
      • Standardization activities and attending SMG2/3GPP meetings within ETSI
      • Rake receiver design including channel estimation, acquisition, and tracking for realistic channel conditions.
      • Four patent applications have been filed based on my work with UMTS.
    • GSM work: I have worked with design and implementation of a single chip baseband GSM chip-set, where I have designed and implemented the following:
      • Design and implementation of channel estimation and time and frequency synchronization in the GSM baseband chip-set. These algorithms are programmed in a fixed point DSP. The algorithms have been verified through simulations performed in C.
      • Implementation of a soft output Viterbi equalizer and a Viterbi decoder in the GSM chip-set. The Viterbi algorithm was implemented in hardware using VHDL.
      • Implementation of the GSM full rate speech coding functions in the DSP in the baseband chip-set.
      • GSM standardization activities and attending SMG2 meetings within ETSI
    1994-1995: Tutoring job in four graduate classes at Aalborg University, Denmark.

    Educational background:
    1998-2000: I graduated from Aalborg University with a Ph.D. titled “Data Receiver for the Universal Mobile Telecommunications System (UMTS)”. The project dealt with data receivers for wideband CDMA with emphasizes on the following areas:
    • Radio channel simulation and modeling.
    • Analysis of the sampling rate and dynamic range of ADC in the analog interface.
    • A theoretical and practical analysis of the Rake receiver.
    • Investigation and improvement of the channel estimation algorithms for UMTS.
    • Analysis and simulation of the code phase acquisition in UMTS.
    • A practical solution to multi-paths searching and Rake finger management.
    1990-1995: I graduated from Aalborg University with a master's degree in electrical engineering and a specialization in telecommunications in June 1995.
    Master's thesis: My master's thesis concerns capacity analysis of the GSM system when slow frequency hopping is applied. The major issues in my thesis were radio wave propagation (both long and short term fading) and implementation of some GSM protocols. These protocols were mainly power control, slow frequency hopping, handover, and voice activity detection. The thesis was made in cooperation with the Nokia Telecommunications. The thesis was concluded with the grade 11 on a 13-point scale.

    1989-1990: Pre-engineering at Central State University, Edmond, Oklahoma, USA. This year's studies emphasized calculus, physics, and chemistry. The grade point average (GPA) was 4.0 on a 4-point scale for the year. I was honored with the Outstanding Freshman Award in mathematics and the Beginning Achievement Award in physics.

    1987-1988: Graduated from Cashion High School, Oklahoma, USA with a GPA of 3.6 (on a 4-point scale).

    Personal data: I am 48 years old and married with Dorthe. We have two sons; Daniel at 13 years and Peter at 11 year. During my spare time, I enjoy my family and the great outdoors including running, fishing, skiing, hunting, hiking, and sailing.
