Abstract:
|
This paper describes a bit-synchronous
superregenerative receiver suitable for BPSK demodulation.
The output of the superregenerative oscillator (SRO), which
reproduces the phase information of the input signal, is directly
sampled by a D flip flop clocked by a signal derived from the
quench waveform. Analytical background on the response of the
SRO to a BPSK modulated input is presented. A PSpice
macromodel of the receiver is also provided, allowing simulation
in the linear and logarithmic modes of operation. Simulation
results confirm the feasibility of the described approach. Finally,
a proof-of-concept superregenerative receiver, capable of
receiving a BPSK modulated carrier at 27 MHz with
preliminary experimental results is presented. The measured
sensitivity of this receiver is –99.5 dBm for a bit error rate of 10-3.. |
