HIGH POWER EFFICIENCY OPTICAL-WIRELESS TRANSMITTER
摘要
<p>Provided is a high power efficiency optical-wireless transmitter capable of solving problems of low power efficiency, signal distortion due to non-linearity of output, large number of connection terminals, and non-uniformity of optical power intensities of optical sources. The high power efficiency optical wireless transmitter includes: an amplitude-to-array coder converting an amplitude of an electric signal input from a baseband modulator into optical source control signals so as to generate an optical output power corresponding to the electric signal; optical source driver groups driving optical sources based on the optical source control signals of the amplitude-to-array coder; and MMRS (modified mixed radix system) or MMRR (modified mixed radix system with Redundancy) optical source group driven by the optical source driver groups to generate various optical power intensities.</p>
