A single-bit digital non-coherent baseband BFSK demodulator

Recently, we have presented efficient structures for filters that produce an output with a single-bit resolution. As an application and extension of these works a base-band digital single-bit non-coherent binary frequency shift keying (BFSK) demodulator is proposed. This new structure contains no multi-bit multiplications unlike traditional methods of digital BFSK demodulation. The single-bit BFSK demodulator is then simulated using an additive white Gaussian noise channel. As a benchmark the single-bit BFSK demodulator and the theoretical non-coherent BFSK demodulator bit errors are calculated and compared.
