Abstract
Backscatter communication has gained large interest because of its low cost to perform passive wireless transmission and reception. However, phase cancellation can cause communication between 2 tags to fail. Existing solutions scale poorly in hardware size or throughput, as they utilize multiple antennas or a handshake procedure between tags, respectively. This paper introduces Symbol Pair Modulation (SPM) which is robust against phase cancellation by using IQ modulation over the (passive) non-coherent hardware. We will show by analytical expressions and simulations that SPM with DBPSK does not suffer from phase cancellation, and only requires 0.6dB greater Eb/N0 ratio to achieve BER = 10E-3 compared to BPSK with FM0 line encoding.
