Performance Analysis of 8 x 8 MIMO System for LTE-A in Nakagami-m Fading Channel

Presently, International Telecommunication Union Radio Communication Sector is prototyping the system requirements for International Mobile Telecommunications Advanced (IMT-A) [1]. Achieving 100 Mbit/s in a fast mobility and 1 Gbit/s in a slow mobility conditions [2]. While 3rd Generation Project Partner (3GPP) may exceed this requirement. So the peak data rate is becoming the prime focus of contemporary specification. Presented work mainly focuses on the most promising technique to elevate wireless communication channel capacity i.e. Multi Input Multi Output(MIMO) antenna system. The observations are simulated for indoor environment. MIMO system is envisioned to provide the highest data rate and Quality of Service (QoS) as per given specification. This paper describes the performance analysis of 8x8 MIMO system considering Nakagami-m fading channel probabilistic model and Water Filling sub-band power allocation algorithm.
