Performance analysis of Open and Closed Loop Spatial Multiplexing in LTE Downlink Physical Layer

LTE is the evolutionary step towards fourth-generation mobile to cope up with the increasing throughput requirements of the future wireless cellular systems. This paper investigates the performance of LTE Downlink Physical Layer. LTE utilizes MIMO data transmission to provide spatial diversity and spatial multiplexing, to obtain higher channel capacity, compared with traditional SISO system. Performance Analysis of LTE MIMO is carried out with different antenna configuration. The Link Level cell throughput analysis for Open and Closed Loop Spatial Multiplexing is carried out with LTE Link Level Simulator for 2×2 antenna configuration.
