A serial information signal is converted to groups of bits and loaded to parallel processing branches based on bit rates of the parallel processing branches. Each branch is configured to encode the associated group of data bits on the associated tone. A first bit rate and modulation and power allocation to a first branch of the branches may be different from a second bit rate and modulation and power allocation to a second branch of the branches. To recover the incoming data, the encoded signal may be parallel-processed using branches with different demodulation formats and provide the serial data stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for discrete multi-tone transmission with multiple modulations","description":"Optical network devices and method for optical network communications in discrete multi-tone (DMT) are provided.
