A system and method for providing dynamic channel equalization in V2V and V2I communications systems. The method includes separating the channel bandwidth of a message into a plurality of subcarriers having different subcarrier frequencies, where the subcarriers include data subcarriers and pilot subcarriers. The method demodulates the message in the receiver to extract symbols from the message and determines channel estimation frequency responses using a least-squares estimation process and the extracted symbols for the pilot subcarriers. The channel estimation frequency responses of either the pilot subcarriers, the pilot subcarriers and some data subcarriers, or the pilot subcarriers and all data subcarriers are used to generate updated channel estimation frequency responses, and a new channel estimation frequency response is generated for each extracted signal using a previous channel estimation frequency response and the updated channel estimation frequency response. The extracted symbols are equalized using the new channel estimation frequency response.
