Abstract

a configuração de conformação de feixe é alterada durante um prefixo cíclico que precede um período de símbolo. por exemplo, a configuração de conformação de feixe para um transmissor pode ser alterada durante um prefixo cíclico de multiplexação por divisão de frequência ortogonal (ofdm) que precede uma janela de transformada de fourier rápida (fft). desta forma, não há perda de dados de sinalização devido ao transmissor reconfigurar a sua conformação do feixe.
