Abstract: |
This invention relates to a distribution system down send antenna selection method, which comprises the following steps: to use space multiplexing send project BLAST with each send antenna send out independent sub-data flow and its receive end adopting serial interference-out method to measure gradually; the send end selects the antenna according to average error symbol rate or error code rate expression of each layer in n pieces of base antenna with large-scale channel information reflected from receive end; the send end is to optimize the send power, speed and antenna integration of each antenna to ensure the same error symbol rate and error code rate of each layer. |
