  • Method for bit-loading in a multi-tone DSL system
    Patent number: 8320480
    Abstract: A method and processor in a multi-tone based multi-line transmission system such as a digital subscriber line system. The system includes a pre-processor, also referred to as a pre-coder. The processor iteratively determines an integer number of bits to be allocated before pre-processing. The determination is subject to transmit power constraints taking into account power changes on all lines due to the pre-processor and a required bit error rate.
    Type: Grant
    Filed: September 4, 2006
    Date of Patent: November 27, 2012
    Assignee: Telefonaktiebolaget LM Ericsson (publ)
    Inventors: Boris Dortschy, Rafael Ferrari, Renato Lopes, Murilo Bellezoni Loiola, Ricardo Suyama, Danilo Zanatta Filho, Joao Marco Travassos Romano
