Broadcast communication is considered to be especially important in delivering safety messages in vehicular environments. In this paper, the authors introduce and explore a new method for message broadcast based on repetition. The proposed method uses optical orthogonal codes in vehicular broadcast communications to increase the probability of detection and reduce reception delay. The authors formulate a general framework in which they can examine and evaluate the performance of broadcast schemes based on repetition. This framework is used to compare their method to other proposed broadcast methods.
