Measuring power of a pilot channel of a transmit signal

Abstract

The present invention provides a device for measuring a pilot channel output power of a transmitter, such as a base station transmitting spread spectrum signals. For example, the device may include a detector to deliver an analog signal or a digital number that is proportional to a code domain power of a pilot channel. In one embodiment, a signal metric measuring device may use a detector that measures power of a pilot channel of a transmitter associated with a communication node in a wireless network. The detector may obtain an indication that is proportional to the power of the pilot channel of a transmit signal from the transmitter and use that indication of the power of the pilot channel for controlling a control loop in the transmitter. As a result, a desired level of an output power of the communication node, such as a base station (e.g., Node B) in a wireless network, such as a digital cellular network may be maintained. In this manner, an accurate value for the output power may be obtained, avoiding a long time averaging and use of random or pseudorandom data as modulation content.
