REFERENCE SYMBOL STUCTURE FOR DFT SPREAD OFDM SYSTEM

摘要

PURPOSE: By minimizing the increase of PAPR the reference symbol structure for the DFT sprdead OFDM system multiplexes data symbol and reference symbol in the same OFDM symbol. CONSTITUTION: Data symbols(310, 311, 312, 313) and reference symbols transformed the DFT are multiplexed in the frequency domain. It alternates with reference symbols and data symbols are multiplexed. Data symbols transformed DFT cope with odd-number subcarriers. Reference symbols cope with even numbered turn subcarriers.
