Demodulation of RF signal aggregating four non-contiguous frequency carriers
ICECS（2014）
摘要
This paper demonstrates that it is possible to demodulate a RF signal composed of four aggregated frequency bands by a single demodulator, named "Three Phase Demodulator (TPD)". Measurements results will be analyzed in the case of 4 carriers modulated by two different modulation formats (QPSK and 16-QAM). The bandwidth of each modulated signal is 5 MHz and offers an overall bit rate of 128 Mbps.
