nach der Bestellung gedruckt Neuware - Printed after ordering - Les codes LDPC (Low Density Parity Check) sont l'une des techniques de codage par blocs qui peuvent approcher la limite de Shannon à une fraction de décibel près pour les blocs de grande longueur. Dans de nombreux systèmes de communication numérique, ces codes ont de forts concurrents des turbo-codes pour le contrôle des erreurs. Les performances des codes LDPC dépendent de l'excellente conception de la matrice de contrôle de parité et de nombreuses méthodes de recherche ont été utilisées par différents groupes d'étude pour évaluer les performances. La méthode de construction en champs finis est utilisée ainsi que diverses techniques comme le masquage, la dispersion et la dispersion de réseau pour la construction de la matrice de contrôle de parité H. Ces codes construits sont ensuite simulés pour effectuer l'évaluation des performances. La simulation a été faite pour différents taux en utilisant un canal de bruit blanc gaussien additif (AWGN). Dans MATLAB, une bibliothèque de différentes fonctions a été créée pour effectuer la tâche de construction de la matrice de base, de dispersion, de masquage, de construction de la matrice de générateur, etc.…

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
