摘要:The growth of wireless networks in recentyears coupled with applications demanding high datarates. This paper considers feedback and pre-codingdesign for multi-user MIMO in LTE-Advancedsystems. LTE aims to provide improved service qualityover 3G systems in terms of throughput, spectralefficiency, latency, and peak data rate, and the MIMOtechnique is one of the key enablers of the LTE systemfor achieving these diverse goals. In this paper, wepropose a AMC based pre-coding for multiuser multiinputmulti-output (MIMO) systems. Adaptivemodulation and coding (AMC) is a powerful techniqueto enhance the link performance by adjusting thetransmission power, channel coding rates andmodulation levels according to channel stateinformation.
