A optical wireless orthogonal frequency-division multiplexing (OFDM) channel is mainly affected by particle scattering, such as dust, rain, snow, and fog. An atmospheric channel is not as fixed and predictable as a wired channel, but has greater randomness, which distorts a signal passing through it.

摘要

A optical wireless orthogonal frequency-division multiplexing (OFDM) channel is mainly affected by particle scattering, such as dust, rain, snow, and fog. An atmospheric channel is not as fixed and predictable as a wired channel, but has greater randomness, which distorts a signal passing through it.
