摘要: In this article, the amplitude measurement of multiple and simultaneously received linear chirp signals is investigated. The achievable scalability, that is, maximum number transmitted superimposed a receiver can characterize with given target accuracy, explored using simulations. effect duration bandwidth on estimation accuracy scalability inaccuracies affecting realized also discussed. It shown proposed approach competitive respect to access methods, such as frequency-division or code-division access. accurate measurements are even when collected signal superimposition up 20 amplitudes differing by three orders magnitude.
