Aviation Bi-Phase Shift Keying - Automotive Dictionary

Aviation Bi-Phase Shift Keying (BPSK) is a digital modulation scheme used in aviation communication systems. Here’s how it works:

Modulation Process:
Binary Representation: In BPSK, binary data (1s and 0s) is encoded by altering the phase of a carrier signal.
Phase Transitions:
- A 1 is represented by a +90° phase transition of the carrier signal.
- A 0 is represented by a -90° phase transition of the carrier signal.
Functionality: This modulation method ensures that the transmitted signal can be robustly detected and decoded, even in noisy environments, making it suitable for aviation communication where reliability is critical.
Advantages: BPSK is relatively simple and offers strong resistance to noise and signal degradation, which is essential in aviation for maintaining clear and accurate communication.

This modulation scheme is part of the broader family of phase shift keying techniques and is specifically tailored for aviation needs.
