Study of Similar-orthogonal Spread Spectrum Communication System
Hua Zhao · Communications technology · 2011
This paper proposes a simple and practical method for generating multi-dimensional similarorthogonal matrix by using the exhaustion method,and for its similar orthogonal properties with WALSH,it can, instead of WALSH sequence,be used in CDMA system,the number of multi-dimensional similar-orthogonal matrix obtained through the exhaustion method far exceeds the number of WALSH Matrix(only one) with same size,and the size is also larger than that of WALSH matrix with same number of columns,this can greatly increase the user number of CDMA system.Therefore,as compared with the WALSH matrix,this similar-orthogonal matrix is easy and convenient in implementation,thus is of broader practical significance.
