SYSTEM AND METHOD FOR DISTRIBUTED INPUT-DISTRIBUTED OUTPUT WIRELESS COMMUNICATIONS |
摘要 |
PROBLEM TO BE SOLVED: To provide a system and method for compensating for a frequency offset and a phase offset in a multiple antenna system (MAS) with multiuser (MU) transmissions (MU-MAS).SOLUTION: The method may include: transmitting a training signal from each antenna of a base station to one of a plurality of wireless client devices; generating frequency offset compensation data; receiving the frequency offset compensation data at the base station; computing MU-MAS precoder weights based on the frequency offset compensation data to precancel the frequency offset at a transmitter; and computing a plurality of MU-MAS precoder weights based on channel characterization data. |
