    • The invention discloses an adaptive phase shift method in a multi-carrier system, comprising: generating a group of one or more new phase values for corresponding one or more phase shift carriers, PSCs, based on quantization phase values; calculating and comparing a backward maximum power in an evaluation path with the group of one or more new phase values in one timeslot and a forward maximum power in a working path with current phase values in the timeslot; and adjusting phase of the PSCs based on the group of one or more new phase values if the calculated backward maximum power is less than the calculated forward maximum power. An adaptive phase shift apparatus is also disclosed. With the invention, complexity of the implementation is reduced and a small DPS block resource, low Hardware cost, low power consumption is also achieved.
    • 本发明公开了一种多载波系统中的自适应相移方法,包括:基于量化相位值生成用于对应的一个或多个相移载波PSC的一个或多个新相位值的组; 将评估路径中的后向最大功率与所述一个时隙中的一个或多个新相位值和工作路径中的前向最大功率中的一个与该时隙中的当前相位值进行计算和比较; 以及如果所计算的后向最大功率小于所计算的前向最大功率,则基于一个或多个新的相位值的组来调整PSC的相位。 还公开了一种自适应相移装置。 通过本发明,实现的复杂度降低,并且DPS块资源小,硬件成本低,功耗也低。
