Abstract

In this paper, a scheme to assign a unique PN (pseudo noise) code to each vehicle is proposed in order to reduce interference in a DS/CDMA IVC (direct sequence/code division multiple access inter vehicle communication) network. And the scheme how each vehicle acquires PN codes assigned to other is also discussed. In this paper, a common PN code is used to establish an initial communication link [Hattori, K, et al., Nov. 2000] and common code interference suppression using a successive interference cancellation scheme [Tomotaka, N et al., Nov. 1998] by estimating packet reception timing from the vehicle whose reception power is small is examined under the environment where reception power from each vehicle is different (near-far problem is existing).
