Show activity on this post. As part of my diploma thesis I'm implementing digital communication system based on audio transmission in free space (STMF401RE + analog microphone). I'm using BPSK modulation and I've implemented costas loop for frequency and phase recovery and symbol (which is byte in this case) starts detector using correlation ...

BPSK modulation | Binary Phase Shift Keying modulation
https://www.rfwireless-world.com/Terminology/BPSK.html
The simplest BPSK scheme uses two phases to represent the two binary digits and is known as binary phase-shift keying. The resulting transmitted single for one bit time is. S (t) =A* cos (2*pi*fc*t) for binary 1. S (t) =A *cos (2*pi*fc*t+pi) for binary 0. This is regarded as the most robust digital modulation technique and is used for long ...

The BPSK waveform is the NRZ waveform multiplied by √2 cosω. 0. t. we found the power spectral density of the BPSK signal as . G. BPSK (f)=PTb{[sinπ(f-f. o)Tb/π(f-f. o)Tb] 2 =[ sinπ(f+f. o)Tb/π(f+f. o)Tb] 2} Suppose then that we tried to multiplex signals using BPSK, using different carrier frequencies for different baseband signals ...
