英文摘要	The motivation of this paper is to propose a TDD-CDMA system, of which the TS assignment can he freely switched in individual cell for increasing further the band efficiency in adapting to the local asymmetric transmission requirements. The inter-cell interference is analyzed for this kind of operation, in which one finds that the interference of BS to BS imposes the most difficulty for the implementation. For solving this problem, the concept of the frequency reuse is applied to attenuate the interference power in terms of radio frequency (RF) power to a certain amount. In addition, a digital interference canceller is proposed to cancel the remaining interference to a negligible level. Based on the Poisson model of the access, the system capacity is estimated. The results show that the capacities can he increased by a factor of 11% for the DL channel and 27% for UL channel in comparison with the conventional system, i.e. the transmission of UL and DL channel are synchronized for all cells.; Telecommunications; CPCI-S(ISTP); 0
