Abstract

La presente comprende un método de retroalimentacion estadística para la fasciculacion de transmision de transmision y recepcion multiples (MIMO) que comprende la combinacion de informacion del estado del canal y estadística de largo plazo en la derivacion de la matriz de precodificacion. Al menos se observa un parámetro que se puede medir, y se determina un factor despreciable en funcion del parámetro observado.
