Method and apparatus for providing transmit diversity in a wireless communication system

摘要

The wireless communication system transmits signals using radios (205). The radios (205) receive a signal which is formatted for transmission (602). The formatted signals from the radios (205) are divided. One formatted signal is input directly to a transform matrix (207) and a copy of the formatted signal is input to a delay (206) before being input to the transform matrix (207). Transform matrix (207) transforms (604) the input signals into output signals that each contain a portion of the input signals. The outputs from the transform matrix (207) are then amplified (605) using the amplifiers (208). The outputs from the amplifiers (208) are inverse transformed (606) in an inverse transform matrix (209). The inverse transform matrix (209) serves to recombine the portions of the signals originally input to the transform matrix (207). The resulting signals are then transmitted using antennas (210).
