    摘要： A method for assigning orthogonal codes used for a first system and a second system in a CDMA system including channels of the first system for spreading a pilot signal, a sync signal, a paging signal and a traffic signal with a first set of orthogonal codes corresponding to orthogonal code numbers in different rows from a set of orthogonal codes arranged in a matrix of m rows and m columns, and channels of the second system for spreading a second set of orthogonal codes corresponding to orthogonal code numbers different from said orthogonal code numbers for the first set of orthogonal codes. The orthogonal codes for the second system are transmitted at a data rate higher than a data rate of the first system. The method comprises the steps of: assigning orthogonal codes corresponding to the orthogonal code numbers of the orthogonal code set associated with at least one of 2n rows to the channels of the first system, wherein a set of the orthogonal codes are arranged in a matrix of subsets of orthogonal codes and inversed orthogonal codes, each subset including 2n rows and 2n columns; and assigning orthogonal codes corresponding to the orthogonal code numbers of the orthogonal code set associated with at least one of the remaining rows to the second system.

    摘要： A device and method for continuous outer-loop power control on a physical channel which transmits only power control bits and no data while in discontinuous transmission (DTX) mode in a CDMA mobile communication system is disclosed. In the power controlling device according to one aspect of the present invention, a frame error detector detects an error from a frame of predetermined length and generates an error signal indicating whether an error has been generated. A closed-loop power controller compares a threshold with the signal-to-noise ratio (SNR) in each power control group (PCG) in a plurality of periods of the frame and generates power control information according to the comparison result. An outer-loop power controller increases the threshold in order to generate power control information that commands a power increase in response to an error signal indicating the existence of a frame error, and decreases the threshold in order to generate power control information that commands a power decrease in response to an error signal indicating the absence of a frame error. An offset controlling unit, which is connected to the outer-loop power controller, receives gating information about the gated transmission of data in a frame at a predetermined rate, and generates an offset signal, which indicates an offset corresponding to a changed gating rate if the gating rate is changed.

    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.
