Constellation Diagram of BPSK
Fig 1: Constellation Diagram of BPSK
BPSK uses a single orthonormal basis function:
\[ \phi_1(t) = \sqrt{\frac{2}{T_b}} \cos(2\pi f_c t), \quad 0 \le t \le T_b \]
- Binary '1': \( s_1(t) = \sqrt{E_b} \, \phi_1(t) \)
- Binary '0': \( s_2(t) = -\sqrt{E_b} \, \phi_1(t) \)
Energy of both symbols: \( E_b \)
Distance between points: \( d_{12} = 2\sqrt{E_b} \)
The constellation lies on a single axis (in-phase), since BPSK only varies phase.
