- Consider an OFDM system in which 1000 subcarriers are each to be modulated at 1000 bits per second. Assume that each subcarrier is to be modulated using QPSK. (a) What is the symbol transmission rate? (b) How close can the subcarriers be spaced and still be orthogonal? (c) Assume that at least one subcarrier always carries QPSK symbols. What is the lowest data rate that can be supported by this scheme?For data is transmitted over twisted-pair cable, you have these characteristics: A signal's power on the channel is 60 dB, signal attenuation is 2 dB per 100 meters, and average noise power on the cable is 0.15 dB per meter. Answer the following questions: What's the S/N ratio at the end of a 60-meter channel? What's the S/N ratio at the end of a 1.5-kilometer channel? What's the maximum channel length if the receiving device requires at least 25 dB of S/N ratio for reliable operation?In ADSL, the OFDM symbol rate across all subcarriers is 4000 symbols per second. Assume that in the downstream direction, 25 subcarriers use 1024-QAM, 50 use 256-QAM, 100 use 64-QAM and 100 use 16-QAM. What is the overall bit rate
