摘要 针对多载波通信中存在峰均比与系统吞吐量无法同时得到满足的问题,研究了块疏密度对峰均比和系统吞吐量的影响,提出了一种将交织式块分配和集中式块分配相结合的混合子载波分配方案。仿真结果表明,随着块疏密度的减少,系统峰均比与系统吞吐量都会增加,混合子载波分配方案灵活度高,可以设置多个梯度,从而能够在系统峰均比与系统吞吐量之间权衡。 As PAPR and throughput can′t be satisfied at the same time in multicarrier communication. This paper is devoted to re-cover the effects of block sparse degree to the PAPR and throughput and come up with a hybrid subcarrier allocation scheme which combined interleaved block allocation and localized block allocation. The simulation results show that the PAPR and throughput will increase with the decreasing of the block sparse degree. The proposed hybrid subcarrier allocation scheme has an advantage that it is more flexible and can be set to multiple gradients, so it can make a proper tradeoff between PAPR and throughput.
