QUASI-ORTHOGONAL CODE MASK GENERATING DEVICE IN MOBILE COMMUNICATION SYSTEM

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 + x5*x7 + x7*x8 + x1 + x2 + x5 + x7, to generate a mask signal.
