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.
