Channel Emulation System Software
Channel Emulation System Software (CHESS) is application software that emulates real-world RF channel conditions to help engineers validate communication systems in a controlled laboratory environment. CHESS combines model-based simulation with hardware-in-the-loop testing to create realistic, repeatable channel scenarios for link development, integration, and verification. CHESS models Doppler shift, multipath fading, path loss, interference, additive white Gaussian noise (AWGN), delay, and linear distortion. Users can configure static, list-based, or streaming channel conditions, automate tests through a programmable API, integrate custom models or third-party simulation tools, and update multiple RF channels in real time. CHESS supports customizable scenarios for aerospace, satellite, airborne, air-to-ground, air-to-air, and other wireless communication testing.
