Title (EN) SPATIAL PILOT STRUCTURE FOR MULTI-ANTENNA WIRELESS COMMUNICATION
(FR) STRUCTURE SPATIALE PILOTE POUR COMMUNICATIONS MULTIANTENNES SANS FIL
Abstract: front page image
(EN)Spatial pilot to support MIMO receivers in a multi-antenna and multi-layer transmission communication system. A first layer pilot for a single layer transmission is repeated across subbands in a first OFDM symbol and the first layer pilot is also repeated offset from the first OFDM symbol in an adjacent second OFDM symbol. Additional transmission layers may also be transmitted each include a separate pilot generated and repeated in the first symbol and repeated offset form the separate pilot in an adjacent second symbol. The first and second OFDM symbols are then transmitted and received to characterize the receive channels.
(FR)L'invention concerne un pilote spatial destiné à prendre en charge des récepteurs MIMO dans un système de communications multiantennes et multicouches. Un premier pilote de couche pour transmission de couche unique est répété sur des sous-bandes dans un premier symbole OFDM, ce premier pilote étant également répété de manière décalée par rapport au premier symbole OFDM dans un second symbole OFDM adjacent. Des couches de transmission supplémentaires peuvent également être transmises, chacune d'elles comprenant un pilote séparé généré et répété dans le premier symbole, et répété de manière décalée par rapport au pilote séparé dans un second symbole adjacent. Les premier et second symboles OFDM sont ensuite transmis et reçus afin de caractériser les canaux de réception.
