- Error Probability
The error probability for BPSK over an AWGN channel is Pe = Q(
).
- Find the error probability when Eb∕N0 is equal to 10dB.
- What Eb∕N0 is required to achieve an error rate Pe = 10-5.
- Phase Error
With an uncorrected phase error of φ radians, the bit error probability for BPSK is Pe = Q(
).
- For Eb∕N0 equal to 8dB, find the error probability when φ equals π∕6.
- How much Eb∕N0 is needed to achieve the same error probability as in part (a), if no phase error is present.
- Repeat for a phase errors of φ = π∕3 and φ = π∕2.
