Abstract

Recently, frequency-domain equalization for single-carrier transmission (SC-FDE) has been given much attention. For example, the up-link in the 3.9 generation mobile phone long term evolution (LTE) system, an SC-FDMA method using SC-FDE and multiple access will be adopted. However in previous research, there are many papers describing the features and advantages of SC-FDE based on a comparison of SC-FDE and orthogonal frequency-division multiplexing (OFDM) systems. In this paper, we discuss single-carrier transmission equalization in the time-domain (SC-TDE) and SC-FDE in a unified way centered on the Wiener filter based on the minimum mean square error (MMSE) criterion. As a result, we could get useful information and pointers, especially for when we want to replace existing SC-TDE technology with SC-FDE technology.
