    Abstract

    In this paper, we demonstrate the suitability of the super-regenerative receiver in OFDM communication. The well-known property of super-regenerative oscillators to preserve the amplitude and phase information is exploited to detect the OFDM symbols. A new super-regenerative architecture is presented that makes use of both an envelope detector and a phase detector connected at the output of the superregenerative oscillator. The peak-amplitude and phase samples of the generated RF pulses feed the digital processing blocks to extract the data. Through proof-of-concept simulations of a four-subcarrier QPSK OFDM modulation in the 2.4 GHz ISM band, we validate our proposed approach. This study paves way to the use of low-power, low-cost super-regenerative receivers for widely-employed OFDM communications.
