Performance Analysis of Linear and Non-linear Precoding Schemes With Leakage Based Precoding Schemes in Multi-user Mimo Systems

Abstract

Multiple input multiple output (MIMO) system is one in every of the foremost promising wireless technologies which is able to deliver outspread coverage, outrageous throughput and better reliability. It employs multiple antennas at each transmitter and receiver sides so as to induce high spatial diversity gain that successively helps to mitigate fading and provides improved system reliability. MIMO systems conjointly high data transmission rate through spatial multiplexing therefore leads to higher system capacity. Now days, the vital analysis topic is that the study of multi-user MIMO (MU-MIMO) systems. MU-MIMO system is a key technology for future wireless communication systems as a result of these systems satisfies most of the wants of future generations. Such systems have the potential to mix the high throughput accomplishable with MIMO process with the advantages of space division multiple access (SDMA). Joint process of MIMO channels yields maximum diversity regardless of the amount of multi-user interference.
