In this paper, we propose a new media access scheme based on the ARIB STD-T109 designed for ITS com­munications in order to improve the system performance. The proposed scheme is totally compatible with the conventional scheme corresponding to the ARIB STD-T109 and can reduce the required transmission period per frame and the frame collision rate.

In this paper, we analyze Mean Square Error performances of the frequency offset estimator based on the Moose algorithm. From the analytical result, we indicate a possibility of the iteratively offset estimator and propose a modified estimator structure. By computer simulations, we evaluate the proposed iterative offset estimator and a compatibility with(More)
