摘要: 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.
