Abstract :
Conduct research on precoding select algorithm. A precoding matrix index estimate algorithm based on cell reference signal (CRS) was proposed. Simulation had been conducted in a comparable manner. This algorithm can distinguish the MIMO space characteristic effectively and solved the limitation that CRS not to pass through the precoding could not reflect the channel feedback information. Results show that the proposed algorithm performance is closer to ideal precoding feedback scheme.
