ABSTRACT:
Apparatus, and an associated method, for a radio communication system having a sending station and a receiving station. The sending station sends data pursuant to a communication service and ultrawide band signals pursuant to a selected time-hopping sequence. An ultrawide band signal detector is positioned at the receiving station. The ultrawide band signal detects the ultrawide band signal transmitted thereto. Correlation is made between the detected ultrawide band signal and a locally-generated replica signal. Correlations therebetween are used to facilitate various receiving station operations, such as equalization operations upon received data, time synchronization of the receiving station to the sending station, and position determination of the positioning of the receiving station.
