Abstract:
A different ial T urbo-OFDM scheme w ith the combinat ion of Turbo codes, orthogonal f requency division mult iplexing ( OFDM) modulat ion and dif ferent ial detect ion is presented in this paper. The application of dif ferent ial Turbo-OFDM in high-f requency ( HF) data communicat ion is investigated. This new scheme has the advantages of hig h spect rum efficiency and suppression of mult ipath spread, f requency-select ive fading, jamming and noise. Simulation results show that B performance can be improved by this scheme in HF data communicat ion.
