Abstract

"DISPOSITIVO PARA GERAR UMA MáSCARA DE CóDIGO QUASE-ORTOGONAL EM UM SISTEMA DE COMUNICAçãO". Um dispositivo para gerar uma máscara de código quase-ortogonal em um sistema de comunicação. Um contador gera os primeiro ao oitavo sinais de contador x1-x8 representando funções de Bent. Um operador lógico recebe os primeiro ao oitavo sinais e contador x1-x8 e executa uma operação, por exemplo, x1*x2+x1*x3+x1*x4+x1*x5+x1*x7+x1*x8+x2*x6+x2*x7+x3*x4+x3*x5 +x3*x6+x4*x5+x4*x6+x4*x7+x4*x8+x5*x7+x7*x8+x1+x2+x5+x7, para gerar um sinal de máscara
