MIMO and TM( Transmission Mode) in LTE
4G Americas have published whitepaper titled "MIMO and Smart Antennas for Mobile Broadband Systems" . The above picture and the following is from that whitepaper Actually MIMO operation is Subset of diffirent Transmission Mode(TM) Below are some terminology used and their meaning MIMO :- MIMO is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation , it is being used in Wi-Fi , 3G (HSDPA+) , LTE , LTE-A(4G) MIMO systems are used to improve the robustness of data transmission or to increase data rates. Typically, a MIMO system(MxN) consists of m transmit antennas and n receive antennas SU-MIMO:- It will provide multiple layers of communications to a handset for increasing of throughput. Each communication layer added to the User will increase the final throughput based on number of layers. Extra layers are been added using extra antennas in space diversity and more Transmitters in Base-st
