20120155571 | METHOD, APPARATUS, AND SYSTEM FOR DATA SIGNAL TRANSMISSION IN MULTI-ANTENNA SYSTEM - A method and an apparatus for data signal transmission are disclosed. A data signal is coded through space-time-frequency coding to form k1 space-time-frequency bit streams. P of the k1 space-time-frequency bit streams are divided into K | 06-21-2012 |
20130044029 | METHOD, APPARATUS, AND SYSTEM FOR CONTROLLING MULTI-ANTENNA SIGNAL TRANSMISSION - A method for controlling multi-antenna signal transmission includes: at a first transmission time, selecting a weight vector of a signal beam whose fluctuation in angle dimension is smaller than a preset value as a first basic weight vector; weighting a signal of each antenna array element in a multi-antenna system by using the first basic weight vector, to obtain a first weighted signal on each antenna array element; and delaying the first weighted signal on each antenna array element for a corresponding set time period, so that the multi-antenna system has different transmission modes at different frequencies, and transmitting each delayed first weighted signal through its corresponding antenna array element. | 02-21-2013 |
