Eritek engineers have a wealth of knowledge and experience in mathematical modeling, signal processing, and algorithm development, and have utilized their expertise in these areas to assist numerous customers in solving challenging problems.  Our staff has a strong understanding of communication theory, control systems, optics, mechanical systems, natural phenomena, and has applied computer modeling expertise to simulate and analyze complex systems from a host of disciplines, such as wireless communications, electrical and mechanical control systems, image processing, optical pointing and tracking, and atmospheric absorption/scattering. In particular, Eritek engineers have experience in simulating and processing RF communication signals and systems at the physical layer, including modulation/demodulation, FEC coding/encoding, carrier and symbol tracking, channel equalization, and channel impairments.

Software Modeling

Eritek combines an extensive knowledge of signals and systems with a proficiency in several computer programming and modeling languages, including C/C++, Python, LabView, Embed (VisSim), Matlab, Simulink, and assembly, uniquely positioning the team to tackle difficult problems.

They have used their knowledge of digital signal processing (DSP) to design, model, and implement unique, sophisticated waveforms, such as shift orthogonal constant envelope modulation (SOCEM) and discrete-time chaotic modulation and detection schemes.  Eritek designed and coded the Embed/Comm communications module for the Altair Embed simulation environment (formerly VisSim), and have used these modules to create software defined radio (SDR) models for SOCEM and other communication systems. The Eritek team has also modeled threat detectors and analyzed the LPI performance of custom RF waveforms.  Eritek has developed software for motor, laser, and IR camera control systems and applied its knowledge of signal and statistical processing to implement image analysis software for feature detection within collected IR images.
