    Abstract: PROBLEM TO BE SOLVED: To provide an orthogonal complex spreading method and its system for a multiplex channel by which a problem of unbalanced power between in-phase channels and orthogonal phase channels is solved, and which has an advantage over complex spreading systems proposed by CDMA-ONE in the U.S. and by W-CDMA in Japan and Europe, from the standpoint of power efficiency. SOLUTION: 'Orthogonal complex spread miodulation' is called an OCQPSK (orthogonal complex QPSK). Data for a multiplex channel and subject to gain and orthogonal Hadamard sequence for each channel, two channel data multiplied with the gain and the orthogonal Hadamard sequence are summed in a complex form, a complex multiplier applies complex multiplication to the value summed in the complex form and the outer orthogonal Hadamard sequence in a complex form, and provides outputs of in-phase information and orthogonal phase information. The in- phase information outputted from lots of blocks is summed to the in-phase information and the orthogonal phase information is summed to the orthogonal phase information, and the result is spread by using a spread code in the orthogonal complex spread method for the multiplex channel.

    Abstract: The present invention relates to a method of automatic reception gain control in a mobile station, and an apparatus thereof. According to an exemplary embodiment of the present invention, in controlling the reception gain in the mobile station, a method of automatic reception gain control in an asynchronous mode is used when the mobile station does not ensure the synchronization with respect to a base station, and a method of automatic reception gain control in a synchronous mode is used when the mobile station ensures the synchronization with respect to the base station. Accordingly, the method of automatic gain control can be applied in combination. In addition, according to an exemplary embodiment of the present invention, when the method of automatic gain control in the synchronous mode is used in the mobile station, it can reduce the degree of gain variation that is changed in the automatic gain control by using a signal that is always transmitted from the base station at a designated time. Accordingly, the reception gain can be efficiently controlled.

    Abstract: An orthogonal complex spreading method for multiple data inputs, each of the data inputs being allocated to either a first group or a second group, comprising steps of: generating first outputs (600) by multiplying each of data inputs in the first group (X 11 ... X n1 ) by a corresponding orthogonal sequence and a corresponding gain, respectively; generating a first output signal (810) by summing the first outputs; generating second outputs (700) by multiplying each of data inputs in the second group (X 12 ... X n2 ) by a corresponding orthogonal sequence and a corresponding gain, respectively; generating a second output signal (820) by summing the second outputs; receiving the first and second output signals in a complex form (900) and complex-multiplying the first and the second output signals by SC(OS 3 +jP-OS 4 ) (900, 300), wherein SC is a spreading code, OS 3 and OS 4 are orthogonal sequences, and P is a predetermined sequence.
