Witrynai.e. the improvement in SNR is simply the difference between the improved SNR and the original SNR (if calculated in dB). All these matlab lines should give you the same … 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
