摘要： The present invention is directed to a handover method, a base station, and a mobile station for a CDMA mobile communication system, to improve the efficiency of inter-frequency handover. Handover is achieved between a mobile station and distributed base stations and the like. The base stations have different traffic channel frequencies. In a normal mode, a signal unit transmitted through a traffic channel consists of four frames. In a compression mode, the base station temporally compresses two normal frames into a single frame period and then transmits the frames twice through the traffic channel. The mobile station switches the reception frequency of a present traffic channel and the reception frequency of a perch channel of the destination base station at intervals of two normal-mode frames at the head of each frame received from the perch channel. The mobile station then restores frames received from the traffic channel in the compression mode to the original frames and processes them. At the same time, the mobile station extracts a system frame number from two frames received from the perch channel.

摘要： A technique used in a mobile communications system. A mobile terminal station transmits a signal subjected to an error-correction encoding processing. Each of a plurality of base stations receives the signal transmitted from the mobile terminal station via the wireless line, performs an error-correction decoding processing for the received signal, and transmits an error-correction decoded signal to a base-station host apparatus via the wired line. The base-station host apparatus performs an error-correction encoding processing for each of the signals received from the base stations, composes the thus error-correction encoded signals into one signal, and performs an error-correction decoding processing for the composed signal. The technique can improve the error rate of a received signal without increasing the amount of signal data flowing between the base stations and the base-station host apparatus.

摘要： Detection of errors in the results of turbo decoding is performed while decoding is being repeated. If absence of errors is detected, the results of decoding are output, even though repetition of the decoding operation is in progress, and further decoding is discontinued. Further, the number of times errors are detected in decoded results when decoding has been performed a set number of times is monitored and the decoding operation is executed again if the number of times errors are detected is equal to or less than a set value. Further, one of first and second decoded results output from first and second elementary decoders that construct a turbo decoder is selected as appropriate and is then output.
