In September 2005, Radix Technologies Inc was acquired by Argon ST. Radix Technologies, Inc. is in development of advanced signal processing, digital adaptive beamforming, and null-steering technologies. These techniques can be applied to a variety of real world problems, such as signal reconnaissance, where signals of interest are buried beneath noise and interference. These techniques are also applicable to telecommunications systems, which require high spectral efficiency and multipath mitigation for enhanced quality.
