This paper investigates the encoding of vehicular position information using predictive algorithms in inter-vehicle communications (IVC) from the source- and channel-coding viewpoints. Assuming the 15-mode vehicular driving model, three types of schemes are compared: (1) an ordinary pulse-code modulation (PCM) scheme that transmits position information every sampling period, (2) predictive coding schemes, and (3) a novel scheme using predicted information. This paper estimates the decoded errors caused by transmission errors, when position information obtained from a positioning system is transmitted. Simulation results show that the novel scheme is effective as a coding scheme in IVC.
