抜粋

In order to increase the channel capacity of CDMA (Code Division Multiple Access) mobile and personal communication systems, a new time diversity CDMA scheme that employs orthogonal modulation is proposed. The time diversity CDMA scheme with orthogonal modulation reduces the required Eb/(No + Io) by 5dB at Pe = 10-2 in Rayleigh fading environments with fDT (the product of Doppler frequency and one symbol duration) values ranging from 0.002 to 0.02. This improvement in required Eb/(No + Io) significantly increases the channel capacity of CDMA communication systems that have time varying channels. In addition, the computer simulation results show that the required time delay values of the time diversity scheme are reasonably short (20-100 symbols for 10kbps transmission) for fDT values ranging from 0.002 to 0.02.
