Duisburg Area, Germany

Worked on optimum linear transmit processing based on partial channel knowledge in MIMO communication systems. The concept of robustness (offering the best performance for the worst-case mismatch) was used to design robust transmit eigen-beamformers which were combined with orthogonal space-time block codes to benefit from inaccurate channel feedback.

Chapel Hill, North Carolina

Worked on the development of the IEEE 802.11a baseband solution based on a parallel 2x2 DSP core. This included a fast parallel 64-point IFFT/FFT algorithm, a robust and efficient timing recovery algorithm, course and fine carrier-frequency offset estimation, channel estimation, and pilot tracking.

Greater Minneapolis-St. Paul Area

Conducted research in the area of radar search strategies which resulted in the formulation of the off-line beamform design problem and the design of beamforms for optimal off-line radar target localization using multi-dimensional constellations obtained by rotations of Simplex structures. Also, introduced a recursive geometrical optimization approach for.

Giza, Egypt

Worked on the topic of Arabic phonetic speech segmentation; a pre-processing stage for speech verification. This phonetic segmentation system was built using C language. The system included computing the LPCs using the Levinson-Durbin recursion, constructing a codebook for Arabic phonemes using vector-quantization, estimating the parameters of the HMM.

Designed and developed micro-controller based systems for data acquisition and control using Zilog Z8 micro-controller assembly language.
