Radios are fundamental communications systems for various applications, including public safety, aviation, satellite, cellular networks, and tactical operations. Across all use-cases, challenges such as propagation delay, Doppler shift, path loss, atmospheric disturbance, and multipath fading inhibit effective transmit and receive operations. The ACE9600 enables accurate and thorough radio link emulation by generating time-varying delay, attenuation, carrier Doppler shift, phase shift, AWGN, multipath fading, and other critical impairments. Simulating various radio link effects offers insight into real-world performance while still in the lab, allowing engineers to identify potential faults and make informed adjustments to improve radio designs.
