Performance analysis of MIMO System capacity with various Receiver Architectures
Progress is aspired by the present-day technologies. Due to such progressions various researches are performed in substantial improvement areas. In the wireless spectrum, end-users ‘amount is increasing day by day that leads to the requirement of enhanced BER values and bandwidth usage. Furthermore, in these modern times, new technologies are proved as research’s crucial point that increases the wireless systems’ capacities. A comparison of their BER performance charts is used to evaluate different combinations of multiple user receivers for determining performance under normal working conditions. In order to use the increased capacity rates, which can be achieved using a MIMO (multiple input and multiple output) configuration, MIMO systems are combined into system. MIMO with technology’s complete dissemination through key attributes and components’ investigation regarding single user communications. Various MIMO receivers’ BER (Bit Error Rate) performance is also investigated. Adding SIC (Successive Interference Cancellation) to the MMSE (Minimum Mean square error) as well as ZF (Zero Forcing) MIMO receiver gives some changes to enhancements of BER value, but such minor change is important while ordering is performed with SIC. This particular paper provides a typical MIMO system. Compared to above-developed user systems, modern systems adopt a multi-user scenario. The present requirement for higher data rates resulted in the various techniques use like OFDM by the industry and the additional use of MIMO capabilities in WIFI (Wireless fidelity) s and CDMA (Code Division Multiple Access).
