Abstract: Multiple-input multiple-output (MIMO) antenna systems have received enormous attention due to their ability to provide linear capacity growth without extra power and bandwidth. With optimum non-linear receivers, the capacity of MIMO channels under a wide range of propagation scenarios has been extensively investigated and has now been well-understood. However, the prohibitive complexity associated with such optimum receivers poses significant implementation challenges for practical systems. In contract, low complexity receivers, such as linear zero forcing (ZF) receivers, are more appealing for many applications.
In this talk, we examine the achievable sum rate of MIMO channels with linear ZF receivers. Specifically, we propose several generic upper and lower bounds for the achievable sum rate, which are then particularized to various Rayleigh and Rician fading channel scenarios. Based on the new analytical results, we gain valuable insights into the impact of various model parameters, such as the number of antennas, spatial correlation and Rician K factor, on the achievable sum rate of MIMO channels with linear ZF receivers.
