DSP Communications, Israel ,                                                     January 1994 - September 1995
Title: Speech Coding Group Leader
DSPC is a cellular technologies manufacturer of cellular phone chipset that includes the cellular network interface and the voice compression. Researching and developing a proprietary multi-rate speech coder at 4-8 kbps. The project included C simulations for floating-point and fixed-point arithmetic as well as Vector-Quantizer (VQ) design for each rate and research of various LSP quantizers. Leading the development and implementation of PDC's PSI-CELP and VSELP standards on the company's chipset (masked on TI's TMS320c54x). Developing a noise-canceller for digital-cellular phone. The PDC chipset has become the flag ship of the company. Oded's contribution was the key in turning DSP Communications, from a poor company in 1994, into a very successful one, leading to a $1.6 billion acquisition by Intel.

Optisk Laboratorium: Copenhagen, Denmark ,                                          July - September 1988
Title: Summer Associate
Optisk Laboratorium manufactures optical filters. This process is done using big and noisy evaporation chamber. It is operated using a highly noisy output curve, which reflects the optical filter's layers. In order to control this process automatically, Oded built some hardware and wrote software for filtering and predicting the curve. The estimated curve was used for switching the control of the evaporation process.
