Apparatus and method for measuring noise power in a CDMA mobile communication system |
摘要 |
A noise power measuring system and method for a base station receiver are disclosed. In the system and method, a received signal is despread and the noise power of the despread received signal is estimated. An orthogonal code generator generates a noise power measurement orthogonal code, which is orthogonal to all the orthogonal codes presently being used by the mobile station. A correlator connected to the orthogonal code generator performs a correlation operation between the noise power measurement orthogonal code and the despread received signal. A noise power measurer connected to the correlator, measures the noise power from the output of the correlator.
