Abstract: Coded antenna arrays and associated methods, apparatus and systems are disclosed. Signals transmitted by a client device are received at a plurality of antennas or antenna elements in an antenna array. The received signals are coded using codes such as orthogonal codes and pseudorandom number sequences under which the codes are selected to enable extraction of individual received signals. The coded signals are then combined to form a combined coded waveform that is processed using shared receiver circuitry. The shared receiver circuitry is configured to extract the signals received at each antenna using the codes used to code the received signals. Use of multiple client devices is also supported, with the receiver circuitry further configured to filter out signals received from individual client systems and calculate the phase and magnitude of the signals as received at each antenna.
