A New Method to Construct OVSF Codes Based on Jacket Matrices

자켓행렬에 의한 OVSF 부호 설계의 새로운 방법

Orthogonal Variable Spreading Factor codes are used as channelization codes in WCDMA. In this particular paper, we present a new OVSF codes which is generated from the Jacket Matrices for DS-CDMA systems. The simulations result shows that the purposed OVSF can efficiently reduce the peak values of the correlations than the conventional HOVSF without orthogonality loss. It will be useful to detect the multi-user system under the asynchronous system and save the power of transmission.
