Abstract:
1. A transmitter, comprising a transmission channel processing module for obtaining gains of respective sub-channels; a first transmission preprocessing module for performing a first transmission preprocessing on transmission data transmitted over a spatial sub-channel with a high gain, based on a processed result from the transmission channel processing module; a second transmission preprocessing module for performing a second transmission preprocessing on transmission data transmitted over spatial a sub-channel with a low gain, based on a processed result from the transmission channel processing module; a summing module for summing up the transmission data processed by the first transmission preprocessing module and the second transmission preprocessing module respectively; and a transmitting antenna for the summed transmission data, wherein the first transmission preprocessing module is a MIMO (Multiple Input and Multiple Output) transmission preprocessing and coding module, which performs a MIMO transmission preprocessing and coding on the transmission data transmitted over the spatial sub-channel with the high gain; the second transmission preprocessing module is a signal processing module of STC (Spatial-Temporal Coding) combined with pre-coding, in which the transmission data transmitted over the spatial sub-channel with the low gain are processed by STC, and then processed by pre-coding, wherein the transmission channel processing module obtains a MIMO channel state information estimation H the transmission channel processing module obtains parameters for the MIMO transmission preprocessing and coding module and the STC combined with pre-coding signal processing module, by exploiting the MIMO channel state information estimation H the transmission channel processing module performs SVD (singular value decomposition) on the MIMO channel state information estimation H
