Abstract
Un esquema de transmisión "potencia adaptable circular" (PAC) que puede respaldar tanto a la transmisión en múltiplex espacial como a la diversidad de transmisión para los sistemas de portadoras múltiples de entrada múltiple-salida múltiple (MIMO), y tiene una cantidad de características deseables, que incluye la capacidad para: transmitir un número variable de flujos de símbolos, proporcionar diversidad de transmisión para cada flujo de símbolos trasmitidos, respaldar el uso de una técnica de estimación de interferencia codificada en el receptor, y utilizar la potencia de manera eficiente. En un método, por lo menos un flujo de símbolos es recibido para la transmisión en una pluralidad de sub-bandas y a partir de una pluralidad de antenas. Por lo menos uno de los flujos de símbolos transmitidos en múltiplex de modo tal que (1) los símbolos en cada flujo son transmitidos a partir de la pluralidad de antenas (por ejemplo, diagonalmente a través de als sub-bandas y de las antenas) y (2) por lo menos uno de los flujos se inicia en la misma sub-banda. Un flujo de símbolos en múltiplex es formado y además procesado para cada antena, y puede ser transmitido a plena potencia disponible para la antena.
