Abstract  Abstract

This refers to a method and apparatus for implementing the space and frequency block encoder (SFBC) in an orthogonal frequency division multiplex (OFDM) wireless communications system. This applies to both a closed loop mode and an open loop mode. In the closed loop mode, the power load and the formation of the own beam are made based on the information of the channel status (CSI). A data stream encoded in the channel is multiplexed into two or more data streams. The power is charged based on the CSI in each of the multiplexed data streams. SFBC encoding is performed in the data streams for each of the subcarriers grouped in pairs. Then, a formation of own beams is made based on the CSI to calculate the own beams in multiple transmission antennas. The power load can be carried out in two or more SFBC coding blocks or in each own mode. Additionally, the power load can be effected through subcarriers or subcarrier groups for weak own modes.
