Adjective
multicarrier (not comparable)
Describing a telecommunications signal that is split into fragments, each of which is transmitted over separate carriers before being recombined
If the large number of subcarriers are used, the bandwidth efficiency of multicarrier system such as OFDM with using optical fiber channel is defined as citation * Factor 2 is because of two polarization states in the fiber. Source: Internet
Efficiency comparison between single carrier and multicarrier The performance of any communication system can be measured in terms of its power efficiency and bandwidth efficiency. Source: Internet
So the bandwidth for multicarrier system is less in comparison with single carrier system and hence bandwidth efficiency of multicarrier system is larger than single carrier system. Source: Internet
There is only 1 dBm increase in receiver power, but we get 76.7% improvement in bandwidth efficiency with using multicarrier transmission technique. Source: Internet
