Radio frequency identification (RFID) that can identify an object or person wirelessly using electromagnetic radio propagation. The rapid growth of RFID system there are many works toward software defined radio (SDR) in nowadays can be configured easily to the performance required for different environments. However, there are many still problems as effect to wireless channel characteristic of communications. The multipath fading is cause of interference in RFID microwave bands increasingly. There are several different ways to solve this problem. Therefore, this paper we propose software-defined beamforming to improve the interference signal on the received side. In addition, we propose adaptive blind algorithm to amplitude and phase signal weighting for multi-tag come in analytical over rician fading channels. Therefore, as the results we have shown performance evaluation of bit error rate (BER) and constellation diagram for confirmation. |
