| Zusammenfassung: | The multi-antenna emission system comprises: a space-time process unit to process input data flow and output multiple frequency-domain signal data flow, a modulation unit for OFDM modulating to output relative time-domain signal flow; a data flow separation unit to select emission antenna group for every time-domain signal flow and allocate data to relative emission antenna group, and a cycle delay emission module to circular delay all time-domain signal flow on antenna groups. This invention can obtain both space and frequency diversity gains. |
