    • A base station (28) included in a radio access network of a telecommunications system has two diversity antennas (44A, 44B) for a cell/carrier utilized in a sector served by the base station which are respectively involved in transmission of two branches of a radio link signal of the cell/carrier between the base station and a user equipment unit (30). Two branches of signal processing hardware respectively process the two branches of the radio link signal to yield two respective processed branches of the radio link signal. A rake receiver (62, 262) measures the delay difference between the two processed branches of the radio link signal, and uses the measured delay difference for various purposes. For example, some embodiments of the invention use the delay difference between the two branches as measured by the rake receiver to compensate for a delay difference which exists between the two processed branches of the radio link signal. When measuring the delay difference between the two branches of an uplink radio signal, a rake receiver (62) at the radio base station is employed. On the other hand, when measuring the delay difference between the two branches of a downlink radio signal, a rake receiver (262) at test user equipment unit (30T) is employed.

    • In a method for measuring the quality of an orthogonal transmit diversity signal in a wireless communication system, wherein the orthogonal transmit diversity signal is produced by a transmitter (20) having first and second radio frequency diversity signals for transmitting from the first and second transmit antennas (60 and 62), a radio frequency sample signal that represents the sum of the first and second radio frequency diversity signals is produced. The radio frequency sample signal is then down-converted (86) to produce a down-converted signal having first and second components corresponding to the first and second radio frequency diversity signals, respectively. Thereafter, a first time reference of the first radio frequency diversity signal is recovered (88) from the first component. Finally, a characteristic of the second component that is indicative of a difference in delay between the first and second radio frequency diversity signals is measured (90, 94 and 54) using the first time reference.
