Multicarriertekniikka
Multicarriertekniikka, often translated as multicarrier technology, is a broad term encompassing various communication techniques that divide a data stream into multiple sub-carriers, each modulated and transmitted independently. This approach offers several advantages over single-carrier systems, particularly in combating the detrimental effects of frequency-selective fading encountered in wireless and wired channels.
The most prominent example of multicarrier technology is Orthogonal Frequency Division Multiplexing (OFDM). OFDM divides the
Another related technique is Discrete Multitone (DMT), which is essentially OFDM applied to digital subscriber line
The benefits of multicarrier technology include robustness against multipath propagation, efficient spectral utilization, and simplified receiver
