Similarities between bpsk and bfsk
  1. What are the similarities between BPSK and BFSK?
  2. Is QPSK and BPSK same?
  3. Why do BPSK and QPSK manifest the same bit error probability relationship?

What are the similarities between BPSK and BFSK?

So FPGA based BPSK and BFSK modulators use same source on FPGA, BPSK modulator is only shown in Figure 16. Both BPSK modulation technique and BFSK modulation technique resource utilization, power on FPGA and these modulation techniques are same during data transfer time.

Is QPSK and BPSK same?

QPSK devices modulate input signals by 0°, 90°, 180°, and 270° phase shifts. BPSK devices modulate input signals by 0° and 180° phase shifts. Both QPSK modulators and BPSK modulators are used in conjunction with demodulators that extract information from the modulated, transmitted signal.

Why do BPSK and QPSK manifest the same bit error probability relationship?

The probability of error is identical for BPSK and QPSK because the BER has been measured in terms of signal to noise ratio per bit. in terms of signal to noise ratio per bit.
