摘要:
A device for generating a quasi-orthogonal code mask in a communication system. A counter generates first to eighth counter signals x1-x8 representing Bent functions. A logic operator receives the first to eighth counter signals x1-x8 and performs an operation, for example 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+3x5*x7+x7*x8+x1+x2+x5+x7, to generate a mask signal.
