Description

In mobile radio communications, generally, the phase of carrier is fluctuated hardly on the transmission channel. In this paper, we propose a novel OFDM/CDMA system using differential detection. If the differential detection uses, we don't need to estimate channel characteristics. The proposed CDMA system adopts the spreading code between differential modulation and OFDM, and we evaluate its performances by computer simulations. The differential signal is modulated between the same frequency symbols in each sub-channel of OFDM. And we show that the proposed system is available for multiple access, and evaluate its fundermental performances.
