Because the weights are determined by the correlation of code sequence and estimation error of channels, which can be nearly determined by system load factor, we determine the sub-optimum weights by system load factor through simulations, and substitute the hard-decision symbol function by soft-decision hyperbolic tangent function to decrease the risk of error decision.

由于加权因子取决于前级符号估计的可靠性。也就是取决于扩频码互相关系数与信道估计精度，在随机扩频系统中，估计精度可近似由系统负荷决定，因此可根据系统负荷决定加权因子，以很小的性能降低代价换取计算量的极大降低。同时，为进一步降低误判风险，使用带有斜率控制因子的双曲正切函数代替常规的符号函数。

The importance of the role of these morphogenic substances, as well as their mechanism of action, is evident by the fact that they have been conserved throughout evolution, where different variants can be found to exist in species ranging from worms to fruit flies and up to higher species including humans.

这些形态因子及其作用机理的重要性是显而易见的，事实上，在进化过程中这些因子是非常保守的，不同的物种包括蠕虫，果蝇以及高级物种人类在内，都存在形态因子的不同形式。

At first, we made up an appropriate configuration of design and determined which factors might have effect on slim products. Then we determined control factors and standards of control factors that were set according to the standard of Dr. Taguchi's experimental orthogonal array. With the bigger the better of orthogonal array, L9(3^4), we conducted confirmation procedure on operating factors by use of cypress essential oil on slim cosmetics. The experiment was used to obtain best combination of parameters by S/N ratio and characterizations that were based on the data constructed by Taguchi Methods.
