Implementation Details of BPSK
The implementation details of BPSK carries basic functions in digital modulation techniques, choosing appropriate basic functions and modulation process in BPSK.
Basis Functions in Digital Modulation Techniques
In modulation techniques, we select a group of functions to represent the modulation scheme. These functions are usually orthogonal, to each other. Can be derived through the Gram-Schmidt orthogonalization procedure. By choosing functions we can express any vector in the signal space as a linear combination of them.
Choosing the Basic Function for BPSK
In BPSK the modulation process involves using a sinusoid as the basis function. By adjusting the phase of this sinusoid based on the message bits we can achieve modulation. When transmitting a 1 there is no phase shift, in the carrier signal. However, when transmitting a 0 there is a phase shift of 180 degrees in the carrier signal. This straightforward modulation scheme enables the transmission of data.
Modulation Process in BPSK
In BPSK we represent symbols as phase shifts in the carrier signal during the modulation process. A binary 1 is sent without any change in phase while a binary 0 is sent with a phase shift of 180 degrees. This information about phase shifts is encoded into the carrier signal to facilitate data transmission. The constellation diagram, for BPSK, displays two constellation points positioned along the x in phase). There are no points projected onto the y-axis (quadrature) as BPSK relies on one basis function. The phase of the carrier wave carries all the information being transmitted.

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.
