Abstract

본 발명은 확산대역 이동통신 시스템 등에서 신호간의 간섭 효과를 제거할 목적으로 사용되는 왈시-하다마드(Walsh-Hacdamard) 함수열 생성기에 관한 것으로, 가로열 계수기와 세로열 계수기 출력을 논리곱한 후 그 출력들이 배타적 논리수합수단을 거치게함으로써 최종 출력의 함수열이 왈시-하다마드 함수열이 되게 하는 N차원 왈시-하다마드 함수열 생성기에 있어서, 상기 계수기는 N/M차계수기; M차 계수기; 및 상기 N/M차 계수기측과 M차 계수기측의 최종 출력을 다중화하는 다중화수단을 구비하여 이루어짐으로써 순방향 링크 및 역방향 링크에 사용되는 왈시-하다마드 함수열을 고속으로 생성하는 효과가 있다.The present invention relates to a Walsh-Hacdamard function string generator used for the purpose of eliminating interference effects between signals in a spread spectrum mobile communication system. An N-dimensional Walsh-Hadamard function sequence generator for passing a function sequence of the final output to a Walsh-Hadamard function sequence by passing through an exclusive logical combining means, the counter comprising: an N / M order counter; M-order counter; And multiplexing means for multiplexing the final outputs of the N / M-order counter side and the M-order counter side, thereby producing the Walsh-Hadamard function sequence used for the forward link and the reverse link at high speed.
