Content SummaryThis work studies all necessary signal processing steps in a full-duplex Gen2 reader for RFID tags with Miller-2, 4 and 8 line coding. Relevant prior art focused on FM0 line coding. Synchronization, channel estimation and coherent detection techniques are presented. Symbol-by-symbol detection is studied and respective BER in AWGN is theoretically calculated, showing its equivalence with BER-optimal FM0 coherent detection. Since Miller line coding has memory, maximum likelihood coherent sequence detection is studied, using the Viterbi algorithm. Simulations in Rayleigh fading show that 16-bit sequence detection offers approximately only 1.2 dB advantage compared to symbol-by-symbol at 2/1000 BER. Furthermore, higher lengths offer rather diminishing returns. This finding corroborates famous M. Simon's and D. Divsalar's relevant 2006 conjecture, stating that Miller's sequence detection with "Viterbi would not asymptotically recover a 3 dB advantage". Future work will study other fading channels, including Rice.en
