Method and apparatus for supporting transmit diversity in a receiver

摘要

A method and apparatus for supporting transmit diversity are disclosed. A wireless communication system includes a transmitter having a plurality of transmit antennas and a receiver having at least one receive antenna. The transmitter transmits different pilot code sequences via each of the transmit antennas. The receiver comprises at least one receive antenna for receiving signals transmitted from the transmitter and a plurality of equalizers. Each equalizer is locked onto one of the transmit antennas and processes received samples using a corresponding pilot code sequence. The equalizer may treat user data and pilot code sequence transmitted via all other transmit antennas except the corresponding transmit antenna as interference or alternatively may cancel pilot or pilot and data in parallel or successively.
