PILOT DESIGN FOR LONG TERM EVOLUTION UPLINK MULTI-INPUT MULTI-OUTPUT ANTENNA SYSTEM

摘要

An a kind of uplink subframe of multi-antenna pilot the transmission time-multiplexed wave beam of closed loop transmission specific pilot tone and the specific pilot tone two halves short block of an antenna. The wave beam specifically emits pilot tone as the demodulation/estimation for using same wave beam to provide optimal data as data with interior pilot tone. The specific pilot tone of the antenna sends to provide optimal beam selection with outer pilot tone.
