In order to migrate toward 4G, studies on 3G LTE(Long Term Evolution) have been announced recently in the 3GPP(3rd Generation Partnership Project) and standardization is under way. Therefore, 3G LTE(Long Term Evolution) systems have been designed and developed over many countries. We also have been developing a 3G LTE testbed system at ETRI. 3G LTE system is adopting OFDM (Orthogonal Frequency Division Multiplexing) method, especially 2x2 MIMO (Multiple Input Multiple Output) OFDM and convolutional and turbo encoder for control channels and data channels respectively. In this paper, we describe the structure and implementation method of control channels and data channels of the UE decoder which is being developed at ETRI and propose an efficient implementation method to minimize clock cycle to complete the derate matching algorithm ofshared channel data. ©2008 IEEE.
