Question

Which has same probability of error?
a) BPSK and QPSK
b) BPSK and ASK
c) BPSK and PAM​

Answer 1

Answer:

a-BPSK and QPSK is your answer.

Explanation:

Answer 2

Answer:

BPSK is similar to bipolar PAM and both have same probability of error. 14.

BPSK is used on both carriers and they can be independently demodulated. However, in order to achieve the same bit-error probability as BPSK, QPSK uses twice the power (since two bits are transmitted simultaneously). The modulated signal is shown below for a short segment of a random binary data-stream.

BPSK is similar to bipolar PAM and both have same probability of error.
