| Popis: | In recent years, it is required to realize higher speed and higher quality mobile communication due to the increase in Internet use. Adaptive modulation and coding (AMC) scheme is now commonly implemented to maximize the throughput performance under the given link qualities. Forward error correction (FEC) based link adaptation is effective to improve throughput in a lower SNR regime, however, it immolates maximal throughput in good channel condition. Frequency symbol spreading (FSS) has been proposed that can improve BER even without FEC. It fully exploits the frequency diversity gain by spreading symbol per subcarrier to all frequency components. This paper proposes a new adaptation control scheme for FSS-based OFDM incorporating AMC. Simulation result verifies its maximized throughput performance harvesting both of coding gain and frequency diversity gain. |
