A novel digital baseband beam forming system is disclosed including a plurality of digital baseband beam forming channels configured and operable for connecting via channel ports to a plurality of antenna channels associated with respective antenna elements for at least one of transmitting and receiving through the plurality of antenna elements one or more waveform signals encoding data streams. The digital baseband beam forming channels are configured and operable to apply at least one of phase and time delays of selective magnitudes to baseband signals associated with data streams encoding the waveform signals transmitted and/or received by the plurality of antenna elements, thereby beamforming said waveform signals to produce, by said waveforms, one or more data encoded beams associated with respective directions of propagation and encoding said data streams respectively. The digital baseband beam forming system may be implemented in chip (e.g. Silicon chip) and may be configured and operable for constructing scalable array comprising a plurality of such beamforming chips connectable to a respective group of antenna elements of an antenna array for carrying out at least one of transmitting and receiving beam formed waveform signals by the respective group of antenna elements.

Digital beam forming system and method

Method and system of calibrating antenna array communication are disclosed. A calibration process is used to obtain signatures by at least one antenna element of the antenna array under idealized operational conditions responsive to a calibration sequence transmitted by at least one other antenna element of the antenna array under, to obtain signatures by the at least one antenna element in an operational state of the array responsive to transmission of the calibration sequence by the at least one other antenna element, to compare the signatures obtained under the idealized conditions and in the operational state, and generate calibration data based thereon.
