A Heuristic Optimal Discrete Bit Allocation Algorithm for Margin Maximization in DMT Systems
A heuristic optimal discrete bit allocation algorithm is proposed for solving the margin maximization problem in discrete multitone (DMT) systems. Starting from an initial equal power assignment bit distribution, the proposed algorithm employs a multistaged bit rate allocation scheme to meet the target rate. If the total bit rate is far from the target rate, a multiple-bits loading procedure is...
متن کاملA New Adaptive Algorithm for Bit Allocation in DMT Modems
This paper presents a new algorithm for distributing bits to the subchannels of a DMT modem. The so-called Inverse Robin Hood algorithm converges rapidly and can effectively optimise the overall bit error rate in a non-Gaussian channel. Key-words: Discrete multi-tone modulation, adaptive bit-loading, DSL modems, non-Gaussian channels.
متن کاملDynamic Subcarrier and Bit Allocation for Throughput Maximization in Multiuser Ofdm Systems Using Ant Colony Optimal Algorithm
In this paper, an efficient dynamic resource allocation scheme for multiuser orthogonal frequency division multiplexing (OFDM) systems is investigated. There have been many researches to maximize total system throughput with only limited transmission power. In addition to the limited power, we add required minimum transmission bits for each user as another constraint for the quality of service ...
متن کاملa benchmarking approach to optimal asset allocation for insurers and pension funds
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
15 صفحه اولBit- and power-allocation algorithm for symmetric operation of DMT-based DSL modems
Discrete multi-tone (DMT) based digital subscriber loop (DSL) modems must allocate power and information bits to the discrete tones for quadrature amplitude modulation. The bitallocation (also referred to as bit-loading) algorithms in the literature are designed for modems that operate in the simplex mode in which the upstream and downstream signals use nonoverlapping frequency bands. However, ...
