On Enhancement of Error Detection Capability of Wave Standard

The Physical Layer Convergence Procedure (PLCP) header in the Wireless Access in Vehicular Environments (WAVE) standard is protected from transmission errors over a noisy channel with a convolutional code (CC) and a one-bit cyclic redundancy check (CRC) code, i.e. even parity-check code. The CC and even parity-check code are in charge of error-correction and -detection, respectively. However, the error-detection capability of the even parity-check code is so weak that there may be many undetected errors, which results in significant loss of protocol efficiency and/or delays. The authors are motivated by this issue. The technical challenge is addressed by introducing a new PLCP header which contains a stronger error-detection code. However, for compliance with the WAVE standard, we do not change CC and length of PLCP header, which is possible with a novel puncturing idea. The authors confirm their work by evaluating improvements of various performance measures due to the proposed ideas.
