Using a Sorted QR Decomposition Algorithm for Multiuser MIMO Downlink Transmission
Keywords:
MIMO, Precoder, SQRDAbstract
MIMO is a wireless technology that uses large scale antennas to transfer more data at the same time and to increase
spectral efficiency. To achieve high data rate with less bandwidth we use decomposition algorithm. Among various
de-composition algorithm QR decomposition algorithm outperforms low bit error rate(BER), but the computational
complexity is prohibitively high when the system incorporates large number of antennas. This paper presents a low
computational sorted QR decomposition (SQRD) algorithm for MIMO.SQRD uses precoding technique at the
transmitter which decomposes the channel that can sent in parallel.
