摘要:
对连续Pilot体制的宽带CDMA系统,提出了根据信道衰变速率对专用导码功率动态调整, 从而提高系统容量的方法.该技术使导码与数据码道功率之比下降,对不同业务模型的系统容量均有不同程度的增加.文中对该方法的机理进行了阐述和推导,仿真和数值计算结果证实了该方法的正确性和有效性.
Abstract:
A novel increasing capacity technique for W-CDMA with continuous user dedicated pilot is presented, in which the power level of the UDP (user dedicated pilot) is dynamically adjusted according to the estimated channel fading rate. Theoretical analysis and computer simulation results approve that the influence on receiver performance of pilot power and the one of the integral length of channel estimation in RAKE receiver can be replaced, so long as the fading channel remains its relative stability. So, the UDP power can be decreased when the mobile-station moves slowly. Simulation results indicate that the system capacity is increased to different degree when different services provided.
