摘要: An apparatus that can lower the possibility of failing reception modulation in communication where data is transmitted with and without directivity and prevent deterioration of transmission efficiency caused by retransmission. With this apparatus, a gain control signal multiplex section (203) time division multiplexes a directional transmission signal and a gain control signal. A transmission level control section (204) controls the transmission power level of a gain control signal so that the transmission power level of the gain control signal is smaller than the transmission power level of a directional transmission signal and the received power level of the gain control signal is larger than a received power level of a nondirectional transmission signal at the receiving side, and controls the transmission power level of a directional transmission signal so that the received power level of the directional transmission signal is larger than the received power level of a nondirectional transmission signal and the received power level of a gain control signal at the receiving side.

摘要: A search support apparatus that makes it easy to search for an object and communicate with a communication apparatus which manages the object. In this apparatus, when control section 105 receives object information from demodulation section 102a, it reads object information (search conditions) registered in object information section 103b in condition registration section 103, compares the information with the input object information, generates a control signal for controlling a reporting operation of operation section 106 according to the comparison result and outputs the control signal to operation section 106. Operation section 106 executes a reporting operation according to the comparison result of the object information at control section 105, and is constructed of rotation control section 106a and vibration motor 106b as shown in FIG. 4. Rotation control section 106a controls the intensity or the period of vibration of vibration motor 106b according to the control signal input from control section 105.

摘要: A CDMA communication apparatus wherein resistance against phase noise can be improved without degradation of transmission efficiency. In this apparatus, spread parts (110-1 to 110-n) spread the respective ones of transmission signals (1 to n). Coordinate transformation parts (120-1 to 120-n) interchange the in-phase and quadrature components of the signals as spread for each chip. A multiplexing part (130) multiplexes the n signals as coordinate transformed with known signals used for transmission path compensation. Coordinate transformation parts (250-1 to 250-n) interchange, for each chip, the in-phase and quadrature components of serial signals as outputted from a P/S conversion part (240) such that the coordinate transformations of the coordinate transformation parts (120-1 to 120-n) at the transmission end are reversed. Despread parts (260-1 to 260-n) despread the n signals as coordinate transformed by the coordinate transformation parts (250-1 to 250-n) to output reception signals (1 to n).
