Research on image transmission equalized by dual-mode blind algorithm

The traditional equalization technologies expose some shortages while people put forward higher demand to quality of communication system and transmission rate. Single-carrier frequency-domain equalization (SC-FDE) is becoming a research hotspot in wideband wireless communication area because of its special predominance. In recent years, the research on SC-FDE develops quickly. We take a study on feasibility of building SC-FDE system by comparing performance with orthogonal frequency division multiplexing. This paper takes a study on a dual-mode direct decision-least mean square+modify constant modulus algorithm blind equalization algorithm applied in a single-carrier system. And then, we build the simulation model of image transmission in SC-FDE system and get the direct and better result through the comparative analysis of image.
