Abstract

Antenna array systems and methods for simulating QPSK beam forming having binary phase shifter associated with each transmitting antenna configured to apply a phase shift of 180 degrees to a transmitted signal, and a controller configured to send instructions to the binary phase shifters. The receiving antennas are connected to a post processor comprising a memory operable to save received signals; and a processing unit operable to apply a 90 degree phase shift to selected received signals stored in the memory, and further operable to sum received signals stored in the memory. Optimized antenna array configurations are disclosed.
