Introduction to the coherent detection technique
The BPSK receiver uses a detector of correlation type to demodulate the received signal. Coherent detection requires knowledge of carrier frequency and phase at the end. This information can be obtained through either the Costas loop or the Phase Lock Loop (PLL).
For the purpose of simulation, we assume that the recovery of the carrier phase has already been completed and the frequency reference generated is utilized by the receiver.
Correlation Type Coherent Detector for BPSK
In a receiver, the received signal is multiplied by a reference frequency signal obtained from carrier recovery blocks, like PLL or Costas loop. The resulting output is then integrated over a one-bit period using an integrator. A decision on each integrated bit is made by a threshold detector based on a threshold value. Since the transmitter uses NRZ signaling format the detector threshold is set to 0.
Implementation of the BPSK Receiver in and Python
To implement a BPSK receiver you can choose either or Python. The implementation process includes converting the received waveform to a baseband and utilizing a correlation-based detector. By applying threshold detection you can obtain the demodulated stream. For code examples in and Python for the BPSK receiver please refer to “Digital Modulations using “. Digital Modulations using Python” respectively.
BPSK – Binary Phase Shift Keying
Binary Phase Shift Keying (BPSK) is a widely used modulation technique in digital communication systems for transmitting binary data over a communication channel. It is known for its simplicity and effectiveness, making it a popular choice in applications where the communication channel is susceptible to noise and interference.
