SPATIAL MODULATION METHOD AND APPARATUS IN MULTIPLE ANTENNA SYSTEM, AND DEMODULATION METHOD AND APPARATUS OF SPATIAL-MODULATED SIGNAL

摘要

PURPOSE: Spatial modulation method and apparatus in a multiple antenna system, and demodulation method and apparatus of a spatial-modulated signal are provided to reduce the deterioration of a BER(Bit Error Rate) in the case of a high SNR(Signal to Noise Ratio) by adopting a repeated decoding method sing a previous LLR(Long Likelihood Ratio) value in antenna bit recovery. CONSTITUTION: A dividing unit splits input data into antenna and data bits(302), and a first channel encoding unit performs channel encoding for the antenna bit and the data bit(304,308). First and second interleaving units interleaves first and second symbols(310), and a symbol mapping unit performs the symbol mapping for the symbols(312). A demultiplexer transfers the complex signals of the symbol mapping unit to a specified antenna according to the interleaved first code symbol.
