WebThe digital front-end is the part of the transceiver implementing front-end functionalities like frequency conversion and channel filtering. According to the “SDR doctrine,” the boundary between analog and digital sections of the front-end has to be pushed as much as possible towards the antenna, so as to minimize the presence of analog components. WebThat is, the new block adaptive algorithm is mathematically equivalent to the LMS-DFE algorithm (and hence it features identical performance). At the same time the proposed algorithm offers substantial computational savings as compared to the sample by sample LMS-DFE. Thus the new block DFE turns out to be particularly suitable for applications ...
