基于WiFi的CP-OFDM和OQAM-OFDM系统的性能比较
Performance Comparison of CP-OFDM and OQAM-OFDM Based WiFi Systems
摘要:
在本文中,针对基于802.11a的系统,给出了偏移-QAM-OFDM(OQAM-OFDM)和循环前缀OFDM(CP-OFDM)方案的直接比较。因此,所选择的算法和设计的选择被描述和评估作为一个整体系统的比特和帧出错率(BER/FER)的性能,以及频谱效率和复杂性的存在下的多径传播不同的调制阶数。结果表明,OQAM-OFDM方案具有相似的BER和FER性能,但频谱效率提高了24%,可实现的吞吐量却增加了5倍的计算复杂性。
英文摘要:
In this contribution, a direct comparison of the Offset-QAM-OFDM (OQAM-OFDM) and the Cyclic Prefix OFDM (CP-OFDM) scheme is given for an 802.11a based system. Therefore, the chosen algorithms and choices of design are described and evaluated as a whole system in terms of bit and frame error rate (BER/FER) performance as well as spectral efficiency and complexity in the presence of multipath propagation for different modulation orders. The results show that the OQAM-OFDM scheme exhibits similar BER and FER performance at a 24% higher spectral efficiency and achievable throughput at the cost of an up to five times increased computational complexity.
