    摘要: A spread spectrum communication system for performing spread spectrum communication by superimposing a pseudo noise signal on a transmitted signal. The system comprises traffic detecting means for detecting the traffic of the transmitted signal, and means for changing the clock frequency of the pseudo noise signal in accordance with the output from the traffic detecting means. The system may alternatively comprise transmission quality determining means for determining the transmission quality of the received signal, and means for changing the clock frequency of the pseudo noise signal in accordance with the transmission quality determined by the transmission quality determining means. In operation, the system offers improved S/N ratios where traffic is high or transmission quality is low, saves power where traffic is low or transmission quality is high, and ensures large margins of power control precision for mobile stations near the upper limit of the system's line capacity.

    摘要: A signal power detection apparatus in which a power value can be detected at a high accuracy with a low power consumption includes a pulse generator for generating a timing pulse whose phase is sequentially shifted corresponding to an inputted data signal, a power computing circuit for obtaining the inputted data signal based on a timing pulse and computing a power value of the inputted data signal by squaring a voltage value of the inputted data, and an averaging circuit for averaging the power value of the computed inputted data. A power can be accurately detected without using a high-speed timing clock, and a power value can be detected at a high accuracy with a low power consumption.

    摘要: In order cope with a change of the transmitting capacity in a wireless telephone system. A number of transmission channels are set within the transmission frequency band prepared for each base station. When a communication is made between the terminal equipment and the base station through the transmission channels, at least a first transmission channel and a second transmission channel are set as the transmission channel depending on a class of information to be transmitted. The first transmission channel is set to have a fixed transmitting capacity and the second transmission channel is set so that the minimum transmitting capacity may be defined and the transmitting capacity greater than the minimum transmitting capacity may be set depending on the setting condition of the transmission channels within the transmission frequency band prepared.
