A 27-Mbps, frequency-division multiplexing (FDM) receiver was developed. The 3-channel FDM signal is demodulated in the receiver with a traveling subband demodulator using intra-symbol intermittent demodulation for each subband, which does not require an analog-to-digital converter/fast Fourier transform. Also, the receiver sustains a sensitivity of -55 dBm comparable to that of, e.g., Bluetooth standards (-70 dBm) with respect to 14-dB sensitivity degradation caused by signal bandwidth enhancement, with receiver power dissipation of 3 mW. Furthermore, we have successfully demonstrated energy-exploitation capability from the power of unused FDM signals and interference.
