The modulated signal which includes the carrier component along with two side bands namely USB & LSB (USB contains higher frequency components, whereas the (LSB) has lower frequency components with reference to carrier frequency ) is known as a Double Sideband with Full Carrier system, or simply DSB-FC. In DSB-FC both the sidebands carry the same information.  

Double-sideband suppressed-carrier transmission (DSB-SC) is transmission in which frequencies produced by amplitude modulation (AM) are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed.

In Single sideband system only a single sideband either USB or LSB is broadcast by an antenna where the carrier and the other sideband is suppressed . The DSB-SC modulated signal is passed through a Bandpass filter which results in SSB modulated signal 

Vestigial Sideband Modulation (VSB) refers to the process where the “vestige” part of a signal is modulated alongside one sideband. A vestigial sideband is a form of amplitude modulation (AM) that encodes data in a signal by altering the amplitude of the carrier frequency.
