  A nanoscale receiver utilizing the cantilever of a carbon nanotube has been
developed to detect phase information included in transmitted signals. The
existing receiver consists of a phase detector and demodulator which employ a
reference wave and carrier signal, respectively. This paper presents a design
method to simplify the receiver in structure with enhancing the performance for
the phase detection. The reference wave or carrier signal is not needed in the
receiver via the proposed design method.
