68Power line carrier communication — (PLCC) is mainly used for telecommunication, tele protection and tele monitoring between electrical substations through power lines at high voltages, such as 110kV, 220kV, 400kV.In a PLCC system the communication is established through the power… …
69Double-sideband suppressed-carrier transmission — (DSB SC): transmission in which (a) frequencies produced by amplitude modulation are symmetrically spaced above and below the carrier frequency and (b) the carrier level is reduced to the lowest practical level, ideally completely suppressed. In… …
70Single-carrier FDMA — (SC FDMA) is frequency division multiple access scheme. It can be viewed as a linearly precoded OFDMA scheme, henceforth LP OFDMA. Or, it can be viewed as a single carrier multiple access scheme. One prominent advantage over conventional OFDMA is …
