Abstract

Se proporcionan mecanismos para la transmisión en forma de haz mediante un precodificador. Un método lo realiza un hardware transceptor de radio. El hardware transceptor de radio consta de hardware. El hardware afecta a la transmisión de señales desde el hardware transceptor de radio. El método comprende la adquisición de condiciones de canal de un canal de propagación de radio entre el hardware transceptor de radio y al menos otro hardware transceptor de radio. El método consiste en determinar un precodificador, en forma de una matriz de precodificación lineal, para la transmisión en forma de haz hacia al menos otro hardware transceptor de radio. El precodificador se determina según las condiciones del canal y un modelo de cómo el hardware afecta a la transmisión de señales desde el hardware transceptor de radio. El método consiste en transmitir, utilizando el precodificador, una señal hacia al menos otro hardware transceptor de radio. (Fig. 3)
