WitrynaImproved 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 … The answer to the previous question lies in a scheme called spatial multiplexing. The idea behind spatial multiplexing is that a MIMO multipath channel with a rich scatterer environment can send multiple data streams simultaneously across the channel. For example, the channel matrix of a 4x4 MIMO … Zobacz więcej Antenna arrays have become part of the standard configuration in 5G wireless communication systems. Because there are multiple elements in an antenna array, such wireless … Zobacz więcej The simplest wireless channel is a line of sight (LOS) propagation. Although simple, such channels can often be found in rural areas. Adopting an antenna array under such situations … Zobacz więcej Finally, it is worth looking at how these different ways of using arrays relate to each other. Starting from the LOS channel, as … Zobacz więcej All the channels in the previous sections are line-of-sight channels. Although such channels are found in some wireless communication systems, in general wireless communications occurs in multipath fading … Zobacz więcej

Witryna1 lis 2024 · In a downlink multi-user multi-input multi-output (MU-MIMO) system, much of the existing literature assumes instantaneous CSI at the base station (BS) e.g., as in [2]. Relaying instantaneous CSI to the BS would require a sizable proportion of the bandwidth and hence relaying only statistics of CSI can be a better option for …
