Abstract

In this paper, we propose and evaluate OFDM(Orthogonal Frequency Division Multiplexing)-SSB(Singe Side Band) for improving spectral efficiency. The proposed system is based on OFDM system using DCT(Discrete Cosine Transform) and DHT(Discrete Hilbert Transform). This proposed system transmits a BPSK (binary phase shit keying) modulation signal through a single sideband. Therefore, spectrum efficiency can be improved into 2 times than the conventional DSB(double sided band) communication system. Conclusively, the proposed system can transmits two different BPSK signal with each different single sideband in DSB band.
