Question:
For M-ary PSK, the signal constellation is
For M-ary PSK, the signal constellation is
Show Hint
PSK constellation lies on a circle in complex plane.
Updated On: Jul 2, 2026
- circular
- rectangular
- elliptical
- line
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Signal constellation represents symbol mapping in modulation.
Step 1: PSK principle Phase of carrier is varied.
Step 2: Representation Points are placed on a circle in complex plane.
Step 3: Shape Due to phase variation → circular pattern.
Step 4: Multiple symbols Equally spaced points on circle.
Step 5: Conclusion \[ \boxed{\text{Circular constellation}} \]
Final Answer: \[ \boxed{(A)} \]
