Big Bang v. Cyclic Universe models


A mojor evidence of the big bang theory is cosmic microwave background radiation (CMB) which fills the entire universe. I read recently that about 1% of the static on a static televison channel can be acounted for by the CMB. Does cyclic model have any suggested or discovered evidences that support it as CMB supports Big bang? To my knowledge the only explanation of CMB radiation is that it is radiation left over from the birth of the universe ie. big bang. Does the cyclic model support the CMB theory or can it offer any further insight on CMB?

My guess is that in the cyclic models each crunch would generate a new CMB as the density and temperatures would be the similar to a single big bang. However the evidence at the moment points to the universe never collapsing again due to acceleration of the expansion or due to insufficient mass relative to dark energy if you preer to see it that way. So if the the universe has been cyclic in the past it does not look like it is, this time around.
