Abstract
Time-division duplexing (TDD) detection in wireless distributed communications systems (DCSs) to synchronize TDD downlink and uplink communications. Remote units in the wireless DCS include an adaptive TDD communications synchronization circuit that includes a power detection circuit configured to detect TDD communications signals distinguished from noise. The power detection circuit is configured to adaptively set a noise threshold floor level for TDD downlink communications link by detecting the noise level on the TDD downlink communications link that includes a TDD uplink communication period. The adaptive TDD communications synchronization circuit can also include a symbol edge detection circuit configured to generate an edge trigger signal indicating the symbol edges of TDD downlink communication signals. The symbol edge trigger is used by a TDD frame configuration build circuit to generate a TDD communications frame configuration to control switching of the downlink and uplink communications circuits for synchronizing TDD downlink and uplink communications.
