Abstract

Se proveen técnicas para llevar a cabo codificación por orden de precedencia en un sistema de comunicación de múltiples antenas (por ejemplo, a sistema SIMO, MISO, o MIMO). Una corriente base y una corriente mejorada son codificadas y moduladas de manera separada para obtener corrientes primera y segunda de símbolo de datos, respectivamente en un transmisor. La primera corriente de símbolos de datos es procesada de acuerdo con un primer esquema espacial de procesamiento (por ejemplo, un esquema de diversidad de transmisión o un multiplexado espacial) para obtener un primer conjunto de sub-corrientes de símbolos. La segunda corriente de símbolos de datos es procesada de acuerdo con un segundo esquema espacial de procesamiento (por ejemplo, diversidad de transmisión o multiplexado espacial) para obtener un segundo conjunto de corrientes de símbolos. El primer conjunto de sub-corriente de símbolos se combina (por ejemplo, utilizando multiplexado por división de tiempo o superposición) con el segundo conjunto de sub-corriente de símbolos para obtener múltiples corrientes de símbolos de transmisión para transmitir desde múltiples antenas de transmisión. Un receptor lleva a cabo procesamientos complementarios para recuperar la corriente base y corriente mejorada.
