OFDMsüsteemides
OFDMsüsteemides is a term that refers to Orthogonal Frequency-Division Multiplexing (OFDM) systems in Finnish. OFDM is a digital modulation technique used in modern wireless communication systems. It divides a high-speed data stream into multiple lower-speed streams that are transmitted simultaneously over a number of closely spaced orthogonal subcarrier frequencies. The orthogonality ensures that the subcarriers do not interfere with each other, even though their spectra overlap. This property makes OFDM spectrally efficient.
The primary advantage of OFDM is its ability to combat frequency-selective fading, a common problem in wireless
OFDM is widely employed in various communication standards, including Wi-Fi (IEEE 802.11a/g/n/ac/ax), 4G LTE, 5G NR,
