    Simulation and measurement of multi-carrier and single-carrier frequency domain equalization systems by GAO Zhen1, PENG Ke-wu2, PAN Chang-yong2

    Published 2009-01-01
    “…Chinese national standard of digital terrestrial Television broadcasting(DTTB) was a block transmission system in which the orthogonal frequency-division multiplexing(OFDM) and single-carrier frequency domain equalization(SC-FDE) transmission technologies were compatible.In order to compare the performance of these two technologies over frequency selective fading channel,OFDM and SC-FDE systems using low density parity check code(LDPC) were simulated.Moreover,laboratory tests were carried out to measure the performance of the actual DTTB system.Both the simulation and measurement results show that for the LDPC coded system,OFDM outperforms SC-FDE over frequency-selective fading channels,and the advantage of OFDM becomes more obvious with the deterioration of the fading channel and/or increase of the modulation level.The results are expected to be helpful for the design and optimization of the Chinese DTTB system.…”

    Published 2010-01-01
    “…A motion state-based data delivery scheme(MSD) was proposed for delay tolerant mobile sensor network.By using the broadcasting signal of base station on the frequency of f1,sensor nodes could compute their own motion stated and delivery probabilities which provided the bases for messages transmitting between nodes on the frequency of f2.In order to improved network performance,MSD employed the message survival time and prior forwarding mechanism of own messages to manage the message queue.Simulation results show that the proposed MSD data delivery scheme has a higher message delivery ratio with lower transmission cost and less data delivery delay than other DTMSN(delay tolerant mobile sensor networks) data delivering approaches.…”
