MIMO and MRC:-
o LTE system uses MIMO (multiple input multiple output) as advanced multiple antenna technique in order to achieve the ambitious requirements for throughput and spectral efficiency.
o maximal ratio combining (MRC) : is used to enhance link reliability in challenging propagating conditions when signal strength is low and multipath conditions are challenging.
Downlink MIMO:-
o a 2x2 configuration for MIMO i.e. 2 transmit antennas at the base station and 2 receive antennas at the terminal side.
