Bit error rate performance of a multi-band OFDM UWB RFID system with reader receiver diversity using maximal ratio combiner

Analysis is presented for a UWB RFID communication system using the technique of multi-band OFDM without and with reader receiver diversity. The analysis is provided to find the expression of the bit error rate (BER) of MB-OFDM UWB RFID link with number of receiving antenna at the reader with M-array PAM. BER results are evaluated for indoor industrial UWB environment using several values of MB-OFDM parameters and number of receiver antenna at the reader. The results show that there are significant improvements in the range of a UWB RFID link due to Multi-band OFDM as well as diversity in reader receiver.
