| Abstract(in English) | Spectrum suppressed transmission that increases the frequency utilization efficiency (throughput / required bandwidth) by suppressing the required bandwidth (3dB bandwidth) has been proposed to solve the frequency band exhaustion. However, in spectrum suppressed transmission, transmission quality degrades due to ISI (Inter Symbol Interference) caused by suppressing the required bandwidthto less than the Nyquist bandwidth. In this paper, in order to further improve transmission quality degradation and frequency utilization efficiency, we have proposed spectrum suppressed transmission applying MLD (Maximum Likelihood Detection) in addition to a powerful FEC (forward error correction). Then, we have quantitatively evaluated bit error rate performances and the frequency utilization efficiency in the proposed scheme by computer simulations. |
