An Adaptive Antenna Array with the Time Multiplexed Signal Processing

Radioengineering, 1992
An adaptive antenna array with the digital signal processing requires an independent receiver for each antenna element. This fact significantly influences the cost of the system. The presented paper answers the question what will happen if high-frequency
