Description

technical field

[0001] The invention relates to the technical field of wireless communication, in particular to a method and system for optimizing a multiple-input-output transmission scheme. Background technique

[0002] Since the pioneering work of Telatar and Foschini in the late 1990s showed that MIMO (Multiple-Input Multiple-Output) transmission technology can significantly improve the spectral efficiency of wireless communication, the research on MIMO wireless communication technology has attracted a large number of scholars. MIMO wireless communication technology transmits signals from multiple antennas at the same time by using a certain coding technology at the sending end, receives signals through multiple antennas at the receiving end and combines signals with a certain combining technology, so as to reduce the bit error rate or increase the signal transmission rate. the goal of.

[0003] The essence of MIMO technology is to use the inherent multipath propagation...
