简要介绍了0FDM的单载波调制的有效调制方法,该方法把整个信道化为64子信道,应用16QAM传输,每个子载波均传输相同的比特数4.文中不使用信道编码,而分别使用迫零均衡和最小均方误差均衡.通过仿真,比较这两种均衡的性能.结果表明在0FDM的单载波调制下,在非理想信道以及存在噪声的情况下,迫零均衡的性能要优于最小均方误差均衡的性能.
This paper briefly introduces the effective modulation method of single-carrier modulation for OFDM, which uses the whole channel as 64 subchannels and applies 16QAM transmission, each carrier transmits the same number of bits. The paper does not use channel coding, but uses zero-forcing Equalization and minimum mean square error equalization.The simulation results show that under the single carrier modulation of OFDM, the performance of zero-forcing equalization is better than that of the minimum in non-ideal channels and in the presence of noise Square error equalization performance.
