Fill in the blanks with the best option. (3pts/each a) to f), 2 pts g)), 20 pts a) \{FEC Coding, Modulation, Interleaving\} involves shuffling of bits or symbols at the transmitter so that reverse shuffling at the receiver disperses errors. b) \{QPSK, 8-PSK, 16-QAM\} is the preferred modulation scheme to achieve better reliability when the SINR is low (i.e., radio channel conditions are hostile or poor). c) \{QPSK, 32-QAM, 16-QAM\} is the preferred modulation scheme to achieve higher data rates when the SINR is high (i.e., radio channel conditions are good). d) Changing the modulation scheme from QPSK to 256-QAM increase the data rate by a factor of {2,4,16}. e) What technology is used for combating the ISI? \{Receive diversity, Turbo code, Cyclic prefix . f) The processing gain is if a spreading code of length 32 is used in a CDMA syster g) Frequency reuse value in CDMA is and in GSM is Calculation (5pts/each) 25 pts a) What is the Shannon limit of a channel with bandwidth of 1MHz,S/N=4dB C=log2(1+5)=1 b) P1 is equal to 200W and P2 is equal to 10mW. What is their ratio P1/P2 in dB ? c) What is dBm value of 10mW ? 1010/10=10dBm d) 40dB+10dB50dBm=5DdB50dBm= e) 59dBm(57dBm)=
