ABSTRACT:
Systems, methods and apparatus are provided for equalizing a received multicarrier wireless telecommunications data signal. The wireless signal includes data without accompanying pilot signals, and equalization is accomplished by extracting information from the data, by processing the information in order to obtain equalization indications, and by equalizing the multicarrier wireless telecommunications data signal by modifying indications of the wireless telecommunications data signal using the equalization indications.
