Following the results of [13], operating only on a subset of subcarriers leads to a poor PAR reduction performance compared to the case when operating on all subcarriers.
The combination of transmitter sided precoding with peak-power reduction algorithms is not straightforwardly possible and may lead to a significant degradation of the error performance, to a decrease in PAR reduction capability, or to an increase of computational complexity.
Based on this idea, in this article we introduce a combination of PAR reduction with LRA-THP.
GA based HEM controller performs relatively better in term of PAR reduction; it curtails approximately 34% PAR.
Via numerical simulations, it is pointed out that due to its moderate complexity but very good performance, directed or iterated PTS using combined weighting and temporal shifting is a very attractive candidate for PAR reduction in future multiantenna OFDM schemes.
As can be seen from the numerical results of Figure 4, SLB offers excellent results in terms of PAR reduction performance but also a significant loss in terms of error performance.
The company said it would propose to shareholders a 4-for-1 stock split and a "par value reduction" payment of 8 francs ($4.80) a share in lieu of a dividend for 2000; it paid a dividend of 7 francs a share for 1999.
Based on this idea, the novel PAR reduction scheme selected basis (SLB) is introduced which combines PAR reduction with the precoding approach LRA-THP.
For performance comparison of the PAR reduction schemes discussed in this article, we assess the complementary cumulative distribution function (ccdf) of the PAR, i.e., the probability that the PAR of a given OFDM frame exceeds a certain threshold PARth: (4).
Followed by the novel PAR reduction scheme SLB is introduced.
