OFDMiabased

OFDMiabased refers to systems or technologies that utilize Orthogonal Frequency-Division Multiplexing (OFDM) as a core component of their design or operation. OFDM is a digital modulation technique that divides a high-rate data stream into multiple lower-rate streams, each transmitted over a separate narrow-band carrier frequency. These carriers are orthogonal, meaning they are independent and do not interfere with each other, allowing for efficient use of the available spectrum.

OFDMiabased technologies are prevalent in modern wireless communication systems. Examples include Long-Term Evolution (LTE) and 5G mobile networks, Wi-Fi standards (like 802.11a, g, n, and ac), and digital broadcasting standards such as Digital Video Broadcasting (DVB). The strength of OFDM lies in its ability to combat multipath fading, a common problem in wireless environments where signals reflect off obstacles and arrive at the receiver at different times. By splitting the data across many carriers, OFDM effectively turns a problematic multipath channel into a series of flatter, easier-to-manage channels. This robustness and spectral efficiency make OFDM a foundational technology for high-speed data transmission.
