Narrative:

Departed pgr direct to arg. Requested clearance from mem center to climb into IMC for refresher approach into arg. Center assigned transponder squawk code and cleared to 3000'. After readback ok'd, climbed into actual IMC, reported level at 3000' at 5 NM east of arg. Center called back and was unable to understand transmission. I called back a couple of times but was unable to reach center. After reaching arg VORTAC executed an approach to arg using localizer 17 approach. Inbound on localizer 17 approach I heard center request my altitude. I reported that I was established on the inbound leg of localizer 17 approach to arg and at 1600 MSL. I don't know if center heard me. When clear of cloud on final approach to arg I called center again to report clear of cloud and requested to cancel the IFR plan. Center apparently heard me because I was requested to verify cancellation of IFR plan. I rogered that and heard nothing further from center. Returned from arg to pgr VFR. Summary: unexplained and unexpected loss of communication with center. Executed approach in accordance with loss of communication procedures. Note: pilots in vicinity of pgr monitoring 127.4 (mem center frequency) reported hearing my transmission to center and center calling me. Apparently I could not hear center and center could not hear me but other aircraft could hear both of us.
