초록

In this paper, ranging code collision probability and ranging period which are two important performance measures for code division multiple access (CDMA)-type ranging in wireless broadband (WiBro) system are mathematically derived. Based on the analysis, the appropriate ranging management solution for maintaining the ranging collision probability below a certain threshold level and correctly recognizing the transmitted ranging code against propagation delay is obtained in terms of the number of ranging codes, the number of ranging regions, and ranging period. In this analysis, user mobility features such as speed and moving direction are also considered.
