| Abstract(in English) | This report discusses BER performance of OFDM-DQPSK with delay detection in mobile radio channel by computer simulation. The BER was examined with respect to two kinds of bit error, one occures on a random phase in mobile channel due to delay detection, another is on a inter-carrier-interference (ICI) caused by random phase and frequency offset due to OFDM. As a result, ICI depends on the product of the maximum doppler frequency ƒ_m and OFDM symbol interval T_s, and on the frequency offset rate s. The effect of ICI appears around 10^<-3> in BER, when s>0.1, at ƒ_mT_s=0.01. Further a diversity reception is examined to improve the BER. It effectively reduces the BER, the BER with diversity is less by a two-digit than one without diversity, when ƒ_mT_s and s<0.01, E_b/N_o>20dB. |
