Title (EN) METHOD AND ARRANGEMENT OF DELAY SPREAD COMPENSATION
(FR) PROCÉDÉ ET AGENCEMENT DE COMPENSATION D'ÉTALEMENT DE RETARD
Abstract:
(EN) A method of delay spread compensation, suitable for use in a communication device a having plurality of receiver antennas, is disclosed. The method comprises receiving a plurality of signals, each via a respective antenna, wherein each signal comprises a signal component corresponding to a transmitted signal, and wherein each received signal experiences a respective channel impulse response having a corresponding delay spread; determining estimates of each of the channel impulse responses; calculating post-coding characteristics based on the estimates of the channel impulse responses; and post-coding the plurality of received signals using the post- coding characteristics to produce at least a first delay spread compensated signal. Corresponding computer program product, processing arrangement and communication device are also disclosed.
(FR) L'invention concerne un procédé de compensation d'étalement de retard, adéquat pour une utilisation dans un dispositif de communication ayant une pluralité d'antennes réceptrices. Le procédé comprend la réception d'une pluralité de signaux, chacun par l'intermédiaire d'une antenne respective, chaque signal comprenant un composant de signal correspondant à un signal transmis, et chaque signal reçu faisant l'objet d'une réponse d'impulsion de canal respective ayant un étalement de retard correspondant ; la détermination des estimations de chacune des réponses d'impulsions de canal ; le calcul des caractéristiques de post-codage en fonction des estimations des réponses d'impulsions de canal ; et le post-codage de la pluralité des signaux reçus à l'aide des caractéristiques de post-codage pour produire au moins un premier signal à compensation d'étalement de retard. L'invention concerne également un produit-programme informatique, un agencement de traitement et un dispositif de communication.
