Transmit antenna selection method for std-vertical-bell labs layered space time system

The present invention is in the selection transmit diversity vertical blasting system according to the transmit antenna selection method, in order to improve the overall performance in a conventional selection diversity transmission vertical blast system to select the best antenna transmission performance in a wireless environment, which is necessary to transfer data there was a necessity. The present invention adjusted for this need is the step of one of the plurality of transmit antennas set the antenna combinations for a given number and; Estimating a signal-to-noise ratio of each of the antenna relative to the antenna in combination with; Selecting a minimum signal-to-noise ratio of the signal-to-noise ratio estimated by the antenna in combination with; Selecting an antenna combination having a maximum signal-to-noise ratio of the minimum signal-to-noise ratios and; The through the selected antenna consists of sending the data to the perpendicular blast to reduce the errors occurring in the data using less power to the antenna selection for the wireless environment, there is an effect that for maximum transmission performance.
