Abstract
An ATM digital radio transmission system bi-directionally transmits the ATM cell data from an ATM switch or ATM terminal between the radio base station and a plurality of radio subscriber stations over a radio circuit in a TDMA/TDD system. The TDMA/TDD system consists of a plurality of burst signals, each of which has a different configuration from an ordinary ATM cell only in its header section unique to the radio transmission. Idle cells are inserted to the radio transmission speed. The receiver side detects error bits in the header and payload sections to prevent occurrence of cell loss or the like.
