The CM and PAPR of the aggregated signal are reduced by introducing cyclic time shifts to the OFDM symbols in each of the component carriers (CC). Out of all the aggregated CCs, one of them is chosen to have zero cyclic time shift, meanwhile an optimal amount of cyclic time shifts is introduced into each of the other aggregated CCs. The optimal cyclic time shift for each CC is calculated by applying every possible shift value to all of the OFDM symbols in that CC and working out for each case the CM value when the OFDM signal of that CC is combined with those in other shifted CCs. For each CC, the optimal cyclic time shift is the amount of cyclic shifts applied to that CC which would give the lowest peak “combined CM value”. | 10-27-2011 |
