This paper presents a new a'chievement on SDH radio and the system signature curves are presented which is supported financiaily by the State Natural respective!y.

A radio system transmitted STtM-I ABTE. a MCC scheme against frequency selective fadng(1 55.5ZMbis) with 256QAM modulation within 3OMHz is proposed. Its validity as an effeczke fadig bandwidth is simulated. The system outage countermeasure is proved successfully.
