What is binary phase shift keying (BPSK)?
Binary Phase Shift Keying (BPSK) is a type of digital modulation technique in which we are sending one bit per symbol i.e., ‘0’ or a ‘1’. Hence, the bit rate and symbol rate are the same. Depending upon the message bit, we can have a phase shift of 0 o or 180 o with respect to a reference carrier as shown in the figure above.
How does the Smith predictor work?
The Smith Predictor uses an internal model Gp to predict the delay-free response yp of the process (e.g., what water temperature a given knob setting will deliver). It then compares this prediction yp with the desired setpoint ysp to decide what adjustments are needed (control u).
How does the bpskmodulator work?
The BPSKModulator object modulates using the binary phase shift keying method. The output is a baseband representation of the modulated signal. To modulate a binary phase shift signal:
What is a BPSK object?
BPSK Modulated baseband signal, returned as a column vector or matrix of the same size as the input signal. To use an object function, specify the System object as the first input argument.
Where can I find the constellation diagram of BPSK modulation?

How to design a BPSK modulator?
There are only two in-phase components and no quadrature component. Now, we can easily see that the two waveform of S o and S 1 are inverted with respect to one another and we can use following scheme to design a BPSK modulator: First the NRZ encoder converts these digital bits into impulses to add a notion of time into them.
What is the bit rate of the MATLAB simulation code?
The Matlab simulation code is given below. Here for the sake of simplicity, the bit rate is fixed to 1 bit/s (i.e., T=1 second). It is also assumed that Phased Locked Loop (PLL) has already achieved exact phase synchronization. If you have any comments or questions, you can discuss them below.
