Performance Analysis of MIMO-OFDM of Passive RFID to Maintain a Constant BER

Radio frequency identification (RFID) is wireless communication technology that allows only an objecttobe identification. Themajor components of RFID are readers and tags. In this paper we investigate the Multiple Input Multiple Output(MIMO)setting in the. The advantages of the MIMO RFID technology over single antenna RFID it allows many potential applications inthe area of accurate tracking, identification. So that it improves the reliability and throughput. In this paper we estimate the both bit error rate (BER) and reading range improvement swere observed.
