A new channel equalization method for cooperative vehicular communications

We propose a new channel equalization method equalization for cooperative vehicular communications. It can be applied in cooperative vehicular communications system where each vehicle are only equipped with one antenna. In contrast to those well known HOS-based equalization method, it reduces the demand of bit length greatly, for instance, it only need about 1000 input bits even for 16-QAM signal. Furthermore, its convergence speed is fast and its update rule is simple. Although, a matrix inversion operator is required, the matrix size is small because it is only related to the equalizer length.
