MULTIPLE INPUT-OUTPUT SYSTEM AND SIGNAL RECEIVING METHOD USING THE SAME IN ORDER TO INCREASE TRANSMISSION RATE

摘要

PURPOSE: A multiple input-output system and signal receiving method using the same are provided to reduce the reception complexity of a receiving unit through an ML-DFE(Maximum Likelihood-Decision Feedback Equalizer) method. ;CONSTITUTION: A system receives a transmission signal from two transmission antennas(600). The system divides a channel matrix vector about the received signal. The signal presumes a first symbol. The system calculates an LLR(Log Likelihood Ratio) about the first symbol(610). The system presumes a second symbol through a DFE(Decision Feedback Equalizer) method. The system calculates the LLR about the second symbol(620).;COPYRIGHT KIPO 2011
