Performance Evaluation of BER
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 1, Issue 8
Abstract
Wireless communication is characterized as the transfer of the information between two points physically connected and the separation between them may vary from meters to kilo wireless communication is changing its scenario due to its ease of availability and reliability and lower costs and small sizes and also due to continue research. Multiple Input Multiple Output (MIMO) is a smart antenna technology in the current wireless communication systems, such as 3G and 4G. MIMO can be combined with Orthogonal Frequency Division Multiplexing (OFDM) to improve communica and transmission rate. MIMO OFDM system also gives very good Bit Error Rate (BER) performance. Since MIMO uses multiple transmitting and multiple receiving antennas, so complexity is introduced. Basically used detector MMSE. This paper studies the Vertical Bell Lab Layered Space Time (VBLAST) that is the MIMO system which reduces the complexity and improves gain of the detector. It introduces Successive Interference Cancellation (SIC) algorithm with Minimum Mean Square Error (MMSE) and reduces the detector’s complexity. In this paper we are using MIMO OFDM system with VBLAST algorithm with MMSE equalizer is used to achieve minimum BER in multipath fading channel environment. We are using Binary
