Welcome Guys, We will see
Welcome Guys, We will see MIMO technology in wireless communication in details. What is MIMO in Hindi? MIMO (multiple inputs, multiple outputs) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed.
The existence of multiple antennas in a system means the existence of different propagation paths. Aiming at improving the reliability of the system, we may choose to send same data across the different propagation (spatial) paths. This is called spatial diversity or simply diversity. Aiming at improving the data rate of the system, we may choose to place different portions of the data on different propagation paths (spatial-multiplexing).
advantages of MIMO:
➨The higher data rate can be achieved with the help of multiple antennas and SM (Spatial Multiplexing) technique. This helps in achieving higher downlink and uplink throughput.
➨MIMO based system minimize fading effects seen by the information traveling from transmitting to receiving end. This is due to various diversity techniques such as time, frequency and space.
disadvantages of MIMO:
➨The resource requirements and hardware complexity are higher compared to the single antenna based system. Each antenna requires individual RF units for radio signal processing. Moreover, advanced DSP chip is needed to run advanced mathematical signal processing algorithms.
➨The hardware resources increase power requirements. Battery gets drain faster due to the processing of complex and computationally intensive signal processing algorithms. This reduces battery lifetime of MIMO based devices.
➨MIMO based systems cost higher compared to the single antenna based system due to increased hardware and advanced software requirements.
