multi-beam and electronically steerable antennas, hybrid and full digital beamforming for massive mimo and mmwave systems, satellite communications

mimo communication is a technique for improving the transmission and reception of signals over a channel by exploiting multipath propagation. some examples mimo communications are presented in this section.

  • combine multiple-input-multiple-output (mimo) processing and orthogonal frequency division multiplexing (ofdm) techniques together with beamforming to improve the received signal-to noise-ratio (snr). improved snr reduces the bit error rate.

  • use antenna arrays to improve the snr and capacity of a wireless link.

  • send multiple data streams through a scatter-rich channel by using a set of precoding and combining weights derived from the channel matrix. each data stream can be independently recovered.

  • employ hybrid beamforming at the transmit end of a massive mimo communications system, applicable to both multi-user and single-user systems.
