Abstract


LTE (Long Term Evolution) system proposed by3GPP is the technology streamof choice for the evolution from3G(3rd Generation) to4G(4th Generation), that’squasi-4G. The target peak data rates for downlink and uplink in the LTE system wereset at100Mbps and50Mbps respectively within a20MHz bandwidth, which requiresmore advanced technology of channel coding. In order to meet this high data rate ofuplink in LTE with low-power, this thesis shows the parallel coding scheme of CTC foruplink in the LTE system, which can work at a low clock-frequency with a high datarate.The main research of this thesis is related technologies of physical layer foruplink in the LTE system, including multiple access, radio frame structure, and so on.According to the wireless communication protocol of LTE, the author analysestransport channel processing for UL-SCH, and shows the parallel coding scheme ofCTC.The design of4-bits parallel coding scheme of CTC can greatly improve thecoding efficiency of uplink in LTE system, which is theoretically4times that of theserial coding. Because ping-pong and pipe-line are used in design, with the increasingbits of transport block, the coding efficiency is increased4times than that of the serialcoding, which exceeds the target, thus accelerating the evolution from LTE to4G andsetting the foundation for4G.
