Embodiment 1
[0019] The corresponding solution will be specifically described below by taking the transmitting end as an example with 8 transmitting antennas. Such as figure 1 As shown, when there are 8 transmitting antennas at the transmitting end, the 8 transmitting antennas are divided into two groups, namely antenna group 1 and antenna group 2, each group contains 4 antennas, and antenna group 1 is the antenna {1, 2 , 3, 4}, antenna group 2 is antenna {5, 6, 7, 8}.
[0020] The input data streams are grouped to form data blocks T0, T1, T2..., these data blocks are continuous in time, and the time occupied by each data block is a time period. Space-frequency block code combined frequency switching transmission diversity (hereinafter referred to as SFBC+FSTD) transmission is performed on these data blocks in a time-division manner. For example, after data block T0 is processed by SFBC+FSTD, it enters antenna group 1 and is transmitted from antennas {1, 2, 3, 4}; while data block T1 is ...
Embodiment 2
[0025] In the following, the corresponding solution will be specifically described by taking six transmitting antennas at the transmitting end as an example. Such as image 3 As shown, the input data streams are grouped to form data blocks T0, T1, T2..., these data blocks are continuous in time, and the time occupied by each data block is a time period. Space-frequency block code combined frequency switching transmission diversity (hereinafter referred to as SFBC+FSTD) transmission is performed on these data blocks in a time-division manner. For example, in the first time period, after the data block T0 is processed by SFBC+FSTD, it is sent out from the antennas {1, 2, 3, 4}, such as image 3 the first column in the . In the next time period, after the data block T1 is processed by SFBC+FSTD, it is sent out from the antenna {1, 2, 5, 6}, such as image 3 the second column in the . In the next time period, after the data block T2 is processed by SFBC+FSTD, it is sent out fr...
Embodiment 3
[0027] This embodiment provides a high-order antenna diversity transmission system, including:
[0028] A grouping unit, configured to divide the data stream into time-continuous data blocks, each data block occupies a time period, wherein a time period includes at least the length of one TTI;
[0029] The processing unit is configured to, in each time period, perform space-frequency block code joint frequency switching transmission diversity processing on the data block corresponding to the time period, and send the processed data block to the transmitting unit, wherein Performing space-frequency block coding joint frequency switching transmission diversity processing on data blocks is similar to the solution described in Embodiment 1, and will not be described in detail here;
[0030] The transmitting unit is configured to select 4 transmitting antennas from n (n>4) transmitting antennas in each time period, and transmit the data block from the processing unit from the selec...
