In this project, you are required to use MATLAB/Octave/SCILAB software to simulate BPSK modulation waveform. PSK Modulation Phase Shift Keying (PSK) is the digital modulation technique in which the phase of the carrier signal is changed by varying the sine and cosine inputs at a particular time. PSK is of two types, depending upon the phases the signal gets shifted: - Binary Phase Shift Keying: This is also called as 2-phase PSK or Phase Reversal Keying. In this technique, the sine wave carrier takes two phase reversals such as 0° and 180°. - Quadrature Phase Shift Keying: This is the phase shift keying technique, in which the sine wave carrier takes four phase reversals such as 0°, 90°, 180°, and 270°. BPSK ModulatorThe block diagram of Binary Phase Shift Keying consists of the balance modulator which has the carrier sine wave as one input and the binary sequence as the other input. Following is the diagrammatic representation. Please show all the steps and explaination.

Assume we want to find the best match between an EEG signal and a sinusoidal waveform. • EEG sample frequency was 50 Hz. Generate two sin waves with frequency at 14 Hz and 20 Hz. We limit these shifts to 360 sinusoids, each having 1° difference in phase shift. Calculate the Rxx of these two signals at different phases. We will have to shift the sine wave over the EEG signal to find the best match between the two signals.
