- An optimal algorithm for reducing the peak to average power ratio of ofdm signal
信號峰值平均功率比的優(yōu)化算法 - Space - time block codes ( stbc ) based on orthogonal design has attracts enough attentions in its applications in mimo - ofdm systems for its full diversity exploiting and low coding / decoding complexity . these applications include not only system performance improvement , but also reduction of the peak to average power ratio in mimo - ofdm systems . under these backgrounds , this paper first studies space - time block codes under the single carrier , flat fading situation , discusses the encoding / decoding principle and its performance under different channels . then , the author focused on the performance of space - time codes under time selective and frequency selective channels , uncovered the fundamental cause of how maximum doppler shift and power delay profile influences the performance of space - time codes through deduction and simulation
在上述背景下,本文以單載波,平坦衰落信道下的空時分組碼為切入點,深入分析了其編譯碼原理和在不同信道情況下的性能;以此為基礎(chǔ),后文展開了對空時分組碼在多載波,時間選擇性和頻率選擇性衰落信道下的性能研究,通過理論推導(dǎo)和充分的仿真,揭示了空時/頻分組碼在時頻選擇性衰落信道中的性能變化的根本原因;在以上對多載波系統(tǒng)中空時分組碼的研究的過程中,作者發(fā)現(xiàn)了空時分組碼在降低系統(tǒng)峰平比方面應(yīng)用的可行性,提出了一種降低峰平比的新方法。
