DS-CDMA 셀룰러 시스템에서의 음성검출을 사용한 동적코드할당방식 = Dynamic code allocation using voice activeity detection in DS-CDMA cellular system

다국어 초록 (Multilingual Abstract)

In this paper, we propose a dynamic code allocation strategy using voice activity detection and evaluate the performance of a dynamic code allocation strategy using voice activeity detection in DS-CDMA system. Proposed method allocates code to mobile terminal according to the residual capacity computed by SIR in the base station. In hot spot traffic loading cell, we find that the performance of proposed method is better than that of a fixed code assignment strategy using voice activity detection. Also, we find that the proposed method provide much improvement in blocking probability against the dynamic code assignment strategy withoug voice activity detection.
