Comparing between orthogonal BPSK and differential BPSK
Suppose two modulation schemes, orthogonal BPSK and differential BPSK.
In orthogonal BPSK, we transmit
$$\textbf{x}_{A}:= [x[0], x[1]]^{T}=[1, 0]^{T},$$ and
$$\textbf{x}_{B}:= [0, 1]^{T}.$$
This ...

Modulate a digital message using FSK/PSK combination
I am beginner and I want to modulate the digital signal: 101101 based on the combination: frequency/phase (2 frequencies/2 phases).
For that, I set the 4 possible combinations: ...

What Exactly Is Meant by a 2nd Order Phase Locked Loop?
I'm teaching myself about polyphase clock sync for demodulation of OQPSK. An article from gnuradio.org entitled "Polyphase Clock Sync" makes references to a 2nd order loop. The context seems ...

BPSK demodulation on scilab
I have a csv file which contains the time and magnitude of the BPSK modulated waveform. I now want to demodulate this. Its bitrate is fc/128 (~106 kbit/s) and the carrier frequency is fc/16 (~847 kHz)....

Constellation of BPSK doesn't look as expected
I'm a total novice when it comes to RF beyond basic concepts.
I'm trying to use a HackRF One to pull the data coming off of this transponder, which theoretically transmits data on a 3.59MHz carrier.
I'...

Where to start on creating radio circuits
I'd like to interface with a legacy system that uses BPSK at ~5MHz to transmit data. I understand the basic idea of BPSK - that it's a 180 degree phase shift to represent data - but I'm having a hard ...

what factor (in dB) is the output SNR or signal power affected by this phase error?
In a BPSK system, if at the receiver the oscillator has a phase error of phi =40° i.e. you are
multiplying the received signal with an appropriate cosine signal phase shifted by 40°. Then,
after low ...

Probability of error of 2 identical BPSK channels
we know probability of error of single BPSK system is \$ Q(\sqrt{\frac{2E}{N}}) \$
then what will be the probability of error when two independent identical channels are connected
and hence what will ...

Will a BPSK Demodulator designed for [ 0º , 180º ] symbols work for [ +60º , -60º ] symbols?
I am using an IQ-based digital demodulator circuit IC to receive and decode BPSK signals. It is designed for ordinary BPSK signals, which have [ 0º , 180º ]. However, the signals I am intending to ...
