We carried out a series of binary stellar evolution calculations, in whichthe effect of tidally enhanced wind on the evolution of WD + RG systems isincorporated. The WDs increase their mass to the Chandrasekhar mass limit, andthen explode as SNe Ia. Based on the binary evolution results, we estimated theX-ray/radio (the excess UV) luminosity from the interactions between supernovaejecta and the CSM (the secondary) via some published standard models. We foundthat the X-ray flux may be high enough to be detected for a nearby SN Ia from asymbiotic system, while the radio flux is more likely to de detected when thecompanion is an asymptotic giant branch (AGB) star, and for a first giantbranch (FGB) companion, the radio flux is generally lower than the detectionlimit. For two well observed SNe Ia, 2011fe and 2014J, almost all symbioticsystems are excluded by X-ray observations, but WD + FGB systems may not beruled out by radio observations. The excess UV luminosity resulting from thecollision of supernova ejecta with the RG secondary may be high enough to bedetected if the secondary fills its Roche lobe at the moment of supernovaexplosion. The X-ray/radio emissions are more prevalent in SNe Ia from WD + AGBsystems, although SNe Ia from such systems are rare. The UV luminosity from thecollision of supernova ejecta to RG secondary is high enough, but only 1 inevery few hundred SNe Ia manifests the signal from the collision.
