Abstract

En resumen, de acuerdo con una modalidad, se proporciona un método para transmitir señales. Las formas de onda de señales se transmiten desde al menos dos sectores respectivos. Al menos dos sectores respectivos provienen de al menos dos conjuntos diferentes de un súperconjunto de sectores. Las formas de onda de señal transmitidas incluyen formas de onda de señal al menos prácticamente ortogonales mutuamente al menos a lo largo de una dimensión de señal particular. Una ventaja de tal modalidad, por ejemplo, es la interferencia de señal reducida.
