24-2. Determine the path loss for a 3.4-GHz signal propagating 20,000 m.
24-4. Determine the noise power for a 20-MHz bandwidth at the input to a receiver with an
input noise temperature of 290C.
24-5. For a system gain of 120 dB, a minim
25-4. Which system has the best projected BER?
a. 8-QAM, C/N = 15 dB, B = 2fN, fb = 60 Mbps
b. QPSK, C/N = 16 dB, B = fN, fb = 40 Mbps
a. B = 20 MHz, Eb/No = 19.24 dB
b. FN = 20 MHz, Eb/No = 13 dB
8-QAM, Pe between 10-4 and 10-5
QPSK, Pe better than 10-5
