Embedded/ Communication systems design and development

We have the physical, MAC and Network layer expertise to develop an embedded communication system right from the system requirements specs(SRS) and Algorithm Development phase to the system integration and testing stage. Our expertise covers both wireless as wireline modem design and development space.

Right now we are setting up a design center along with a North American leader in user-end products/equipments for Broadband Satellite Networks, where design from scratch finally leading to implementation for silicon will be the order of the day. Advanced Netwotking and MAC concepts will be applied to reduce the cost and complexity of streaming 2-way multimedia over such networks.

Besides the current activity we have the core competency in the algorithm design and development space for Communication Systems in general. Which means the basics behind Source and channel Coding/decoding, Advanced mod/demod schemes(e.g. DMT, OFDM), Carrier/Timing Recovery(Equalizer tap drift based as well as Phase Lock Loops, Adaptive PLL etc), Adaptive Equalization (both LMS and RLS - Kalman filtering), Channel simulation for both Wireline and Wireless domains.
