Abstract

Se describen sistemas y metodologías que facilitan transmitir y recibir señales sobre las ramificaciones I y Q de un canal de comunicación para mitigar el desequilibrio I/Q potencial; en particular, un dispositivo puede transmitir una señal sobre las ramificaciones I y Q para distribuir la potencia de transmisión sustancialmente de manera uniforme para un canal determinado; el dispositivo puede desmodular los datos con un código o matirz que tiene modificadores reales y complejos teniendo como resultado una señal de ramificación I y Q para transmisión; en la situación donde el canal tiene múltiples recursos, el dispositivo puede alternar o transmitir sobre la ramificación I en un recurso y la ramificación Q en otro recurso para una señal determinada a fin de distribuir potencia; también, el dispositivo puede aplicar un código de mezclado complejo para distribuir una señal sobre ambas ramificaciones I y Q; el dispositivo también puede utilizar QPSK o modulación de orden superior para enviar las señales al mismo usuario.
