WebApr 14, 2024 · Therefore, this paper presents the application of small-scale MIMO precoding techniques for massive MIMO. This paper demonstrates the precoding schemes in promising multiple antenna technologies such as the cell-free massive MIMO (CF-M-MIMO), beamspace massive MIMO, and intelligent reflecting surfaces (IRSs). Block diagram of 32 Tx, 32 Rx massive MIMO radio head featuring Analog Devicesʼ AD9371 transceivers. Conclusion Massive MIMO spatial multiplexing has the potential to become a game changing technology in the cellular communications space, allowing for increased cellular capacity … See more Our thirst for high speed mobile data is insatiable. As we saturate the available RF spectrum in dense urban environments, it’s becoming apparent that there’s a need to increase the … See more Beamforming is a word that means different things to different people. Beamforming is the ability to adapt the radiation pattern of the antenna array to a particular scenario. In the cellular communications … See more In the previous section we’ve described how the CSI (denoted by the matrix H) is estimated. Detection and precoding matrices are calculated based on H. There are a number of … See more An interesting analogy is to consider a balloon being popped at one location and the sound of this pop, or impulse, being recorded at another, as shown in Figure 4. The sound recorded at the microphone position is a spatial … See more
