Better Than

There is difficult to acquire channel state information in massive MU-MIMO system. A downlink pilots precoding scheme I s proposed for efficient channel estimation. With the scheme, the BS precodes the pilot sequences and forwards to all users. The channel estimation overhead of this scheme does not depend on the number of BS antennas, and is only proportional to the number of users. We then derive several precoding techniques which enables us to implement the proposed scheme. Finally in simulation the proposed algorithm is compared with conventional algorithms without precoding training in spectral efficiency. The simulation results show that the proposed scheme performs better than the existing schemes.
