Abstract
We consider here a single-frequency communication system consisting of K possibly moving users distributed in space simultaneously communicating with a central station equipped with a computationally adapted array of n= K antennas. Such a configuration could result if K spacecraft were to be simultaneously tracked by a single DSN complex consisting of an n antennas array. The array employs K sets of n weights to segregate the signals received from the K users. The weights are determined by direct computation based on known position information of the K users. Currently known techniques require (for n=K) about (4/3)K4 computer “operations” (multiply and add) to perform such computations. We develop here an improved technique that accomplishes this same goal in 8 K? operations, yielding a reduction by a factor of K/6.
