Abstract:
1. In an asynchronous code division multiple access (CDMA) communication system using diversity techniques, a power measurement means for a mobile station for measuring transmission power of a base station comprising: a scramble code generator for generating a scramble code which are allotted to the base station; a multiplier for despreading received pilot signal that is spread by the scramble code; an integrator for obtaining amplitudes of the pilot signals by integrating the despread pilot signals for each slot period of pilot symbols, and outputting each amplitude at an end time of each slot period; a squarer for obtaining power values of the pilot signals by squaring each amplitude; a delay means for delaying the power value one slot period; and an adder for adding the power values output from said squarer and the power value provided by said delay means.
