Capacity Evaluation of MIMO System:with and without Successive Interference Cancellation

MIMO is a technique that enhances system performance through antenna arrays at source side and at receiver. These methods can increase the wireless networks' capacity, reach, and dependability. MIMO systems can also be used to mitigate the effects of multipath fading, which is a common problem in wireless communications. MIMO technology is widely used in various wireless schemes, such as Wi-Fi, cellular, and satellite communications. Despite the benefits of MIMO, there are still research challenges that need to be addressed for MIMO systems to be more effective, efficient, and reliable. Overall, the capacity of a MIMO system is a complex and multi-faceted metric that can be evaluated using various techniques (different receiver), depending on the specific operating conditions and requirements. Understanding the performance of a MIMO is the crucial for the design, deployment, and optimization of wireless networks that use this technology. Successive Interference Cancellation (SIC) is a receiver technique has been used for separate and decode multiple signals that are transmitted simultaneously in MIMO which inherently improves the capacity. Hence, this work is focused on estimating the capacity of MIMO with different receiver structures such as; MMSE, Zero Forcing Equalizers incorporated with SIC. The performance of MIMO system has been measured in terms of capacity and compared with MIMO having SIC and MIMO with out SIC.
