Abstract
We investigate the performance of finite-length linear equalizers through calculation of diversity order. We focus on block transmission with cyclic prefix. We prove that, regardless of the channel memory the diversity order of zero-forcing equalizer is one. Through asymptotic outage probability analysis, we observe that the minimum mean square equalizer has a varying diversity order depending on the spectral efficiency.
