Apparatus and method for providing efficient transmission using block coding and cyclic delay diversities in the OFDM based cellular systems

摘要

The present invention is to support the transmit diversity in an orthogonal frequency code division multiplexing / code division multiple access communication system. that, in particular, at least two base station transmit diversity for the same broadcast signal transmitted from a support to effectively provide an apparatus and method. ; This invention comprises at least two or more transmission antennas, the wireless network controller in consideration of the state of the radio channel in a mobile station and multiple base stations in at least three sectors in a cell consisting of s to send information for implementing diversity, sending the base station to the mobile station in the cell that the space-time block coding of data to be transmitted according to the information, and through at least two different cyclic delay is applied to one transmit antenna which it is characterized in that.
