A "power adaptive circular" (PAC) transmission scheme that can support both spatial multiplexing and transmit diversity for multi-carrier MIMO systems and has a number of desirable characteristics, including the ability to: transmit a variable number of symbol streams, provide transmit diversity for each transmitted symbol stream, support coded interference estimation technique at a receiver, and use power efficiently. In one method, at least one stream of symbols is received for transmission on a plurality of subbands and from a plurality of antennas. The at least one stream of symbols is multiplexed such that (1) the symbols in each stream are transmitted from the plurality of antennas (e.g., diagonally across the subbands and antennas) and (2) the at least one stream starts in the same subband. A stream of multiplexed symbols is formed for each antenna and further processed, and may be transmitted at full power available for the antenna.

L'invention concerne un schéma d'émission "circulaire adaptatif en puissance" (PAC) pouvant supporter à la fois un multiplexage spatial et émettre en diversité concernant de systèmes à entrées et sorties multiples (MIMO) à porteuses multiples, comportant un certain nombre de caractéristiques recherchées, y comprises les possibilités: d'émettre un nombre variable de flux de symboles, de fournir une diversité d'émission pour chaque flux de symbole s émis, de supporter une technique d'estimation d'interférence codée à un récepteur, et d'utiliser efficacement l'énergie. Dans un procédé, au moins un flux de symboles est reçu afin d'être émis sur plusieurs sous-bandes et à partir de plusieurs antennes. Le flux de symboles est multiplexé de façon que (1) les symboles de chaque flux soient émis à partir des antennes (par exemple, diagonalement à travers les sous-bandes et les antennes) et que (2) ce flux parte dans la même sous-bande. Un flux de symboles multiplexés est formé pour chaque antenne, puis traité, et peut être émis à la pleine puissance disponible de l'antenne.
