ABSTRACT:
A power measurement means for a mobile station for measuring transmission power of a base station in an asynchronous code division multiple access (CDMA) communication systems using diversity techniques is disclosed. The power measurement means comprises scramble code generators for generating scramble codes which are allotted to each said base station, multipliers for despreading the received pilot channel signals that are spread by the scramble codes, integrators for obtaining amplitudes of the signals by integrating the despread pilot channel signals for each slot period of the pilot symbols, and outputting the amplitudes at the end time of each slot period, squarers for obtaining the power value of the signal by squaring the amplitudes, delay means for delaying the power value one slot period, an adder for adding the power value output from said squarer and the power value provided by said delay means, and switches for connecting to the adder at the end time of every two slots.
