  • Publication number: 20090150115
    Abstract: A mobile terminal device, which is capable of suppressing lowering of a resultant speed when speed data cannot be correctly measured by a rake receiver due to control of AFC or the like, is provided. A comparing section 16 reads a current resultant speed out of a resultant speed storage section 18, and compares the speed data measured by the rake receiver 13 with the current resultant speed. When the speed data is faster than the current resultant speed, the filter section 17 stores the speed data as the resultant speed in the resultant speed storage section 18 as is without performing any filtering process on the speed data measured by the rake receiver 13. When the speed data is slower than the current resultant speed, the filter section 17 averages the speed data measured by the rake receiver 13 and the current resultant speed, and store the averaged speed data as the resultant speed in the resultant speed storage section 18.

  • Patent number: 7447482
    Abstract: It is an object of the invention to provide an antenna selection method for use in a radio communication apparatus in which there is no downlink data loss which occurs due to an antenna selection operation. In a portable telephone set of the CDMA communication system, an antenna selection operation is performed in accordance with the received signal power at each of a plurality of antennas, when the communication with the base station is interrupted. As one example, the antenna selection operation is performed in response to a change of channel between the portable telephone set and the base station. Also, as another example, the antenna selection operation is performed in response to a stop of a transmitting operation in the portable telephone set.

  • Patent number: 7149241
    Abstract: A finger allocating section 5 allocates path timings corresponding to peak positions of a plurality of radio waves to separate finger sections 6 and further decides a path tracking range in each of the finger sections 6 on the basis of respective distances of peak positions in the plurality of radio waves. For instance, when distances between peak positions in a plurality of radio waves received from a base station 30 are narrow, the finger allocating section narrows a variable path tracking range in each of the finger sections 6. Digital base band signals are inversely spread within a path tracking range decided by the finger allocating section 5 among segments positioned before and after a path timing allocated by the finger allocating section 5. In this way, a system and method is provided for positively receiving a plurality of radio waves in a manner that prevents deterioration of reception.

  • Patent number: 7027787
    Abstract: In a mobile communication device, communication can be resumed upon next communication without causing problem even when an AFC control signal becomes abnormal upon interruption of communication. Locked state and unlocked state of an AFC portion is monitored by an AFC monitoring portion 5. Upon interruption of communication, if in unlocked state, a TCXO 1 is controlled by the AFC portion using a TCXO control signal upon preceding locked state. By this, when communication failure is caused by influence of building, tunnel or the like or when communication is terminated, a reference frequency of the mobile communication device does not significantly offset from the reference frequency of a base station to facilitate communication upon next communication.

  • Patent number: 6937642
    Abstract: A common pilot channel-use reverse diffusion unit generates common pilot data using a received digital signal and a common pilot channel-use reverse diffusion code, while an individual channel-use reverse diffusion unit generates individual channel data using the received digital signal and an individual channel-use reverse diffusion code. Power calculating unit converts respective output data items of the common pilot channel-use reverse diffusion unit and the individual channel-use reverse diffusion unit into power values, a larger one of which is then determined by a comparator. A selector unit selects the data item having thus determined larger power value of those output data items of those reverse diffusion units. A channel estimating unit estimates the channel using data symbols of the data item thus selected by the selector unit.

  • Publication number: 20050054340
    Abstract: An A/D conversion section (13) converts analog base band data from a radio section (12) into digital base band data. A despreading section (141) despreads the digital base band data to convert it into symbol data. An RSCP measuring section (142) converts the symbol data into power and measures an RSCP value. An RSCP threshold value judging section (143) compares the measured RSCP value with a preset RSCP threshold value and judges from a result of the comparison whether or not a base station is present. A frequency setting section (144) determines a next search frequency value according to a result of the judgment of the RSCP threshold value judging section. A synthesizer (122) of the radio section produces local data according to frequency data sent from the frequency setting section.

  • Patent number: 6816540
    Abstract: An AFC control apparatus in mobile communication equipment includes a depreading unit, first integrator, and control section. A despreading section despreads the reception signal. The first integrator integrates despread outputs obtained by despreading, of pilot symbols contained in a pilot channel of the reception signal, N (N is a number of 2 or more) consecutive first symbols and N second symbols succeeding the N first symbols, and generates first and second integral outputs. The control section detects any phase shift amount between the first and second integral outputs and controls the frequency of the local signal in accordance with the detected phase shift amount. An AFC control method and mobile communication equipment having the above apparatus and method are also disclosed.

  • Patent number: 6731911
    Abstract: An AFC process is performed even when a mobile station is in a waiting mode in which an incoming call is monitored via a paging channel. Even in the waiting mode, a finger receiver receives a BCCH, and an AFC circuit carries out the AFC process using the BCCH. No reception failure occurs even when a TCXO, i.e., a reference oscillator, suffers frequency fluctuations in the waiting mode.
