SC-CP的迫零均衡和最小均方误差均衡性能比较
Performance Comparison Between Zero-forcing Equalization and MMSE Equalization Based on SC-CP
【摘要】 简要介绍了基于循环前缀的单载波调制,通过仿真比较了在基于循环前缀的单载波调制下迫零均衡和最小均方误差均衡的性能。结果表明在非理想信道及存在噪声的情况下,最小均方误差均衡的性能优于迫零均衡的性能。
【Abstract】 This paper outlines single-carrier with cyclic prefix(SC-CP)and compares the performance of zero-forcing equalization and minimum mean square error(MMSE)equalization based SC-CP.Simulation results show that the performance of zero-forcing equalizer is better than that of the MMSE in non-ideal channel.
