Abstract:
1. A method for eliminating training sequence interference in a time-division duplex (TDD) communication system, the method comprising: receiving a signal having a training sequence and a data block; extracting data from the received signal data that includes a desired data portion and a training sequence portion, the training sequence portion adjacently neighboring the desired data portion and having a length commensurate with a delay spread associated with the training sequence interference, the desired data portion having a length commensurate with a length of the data block combined with the delay spread; obtaining a channel estimation based on the extracted training sequence portion and a known training sequence; equalizing the extracted data based on the channel estimation to produce equalized data; and obtaining desired data by discarding a portion of the equalized data, the discarded portion corresponding to the training sequence portion and having a length commensurate with the delay spread.
