Query: Throughput Performance of 2$\times$2 Mimo LTE Downlink in a Spatial
  Correlation Based Microcellular Channel for Wireless Broadband Networks   Multiple Input Multiple Output (MIMO) technology is going to be a viable
alternative for future generation wireless broadband services in order to meet
the striving requirements for throughput and system robustness. In Long Term
Evolution (LTE), MIMO technologies have been broadly used to get better
downlink peak rate, cell coverage, as well as average cell throughput. In the
present paper a 2x2 MIMO is taken as baseline configuration for a LTE downlink
under a Microcellular propagation scenario considering a non physical
correlation based channel with Poor and rich scattering environment. The
throughput capacity of the downlink is obtained for poor and rich scattering
environments. Besides, two vital aspects of MIMO technique viz Spatial
Multiplexing (SM) and Transmit Diversity (TD) are investigated in order to see
their effect on throughput of the system. The effect of parameters like Speed
of mobile station, number of Multipath, Rician factor (K) on throughput of such
systems is reported and discussed. The investigations reported in this paper
helps in estimating the throughput capacity of LTE downlink under SM and TD
mode.
