  • Patent number: 7379851
    Abstract: A signal power coefficient and a noise power coefficient are calculated for each channel, using parameters which have been optimized up to a small error value by an optimizing means, then using the thus-calculated signal power coefficient and noise power coefficient, there are determined a signal power and a noise power for each channel, and the signal power and the noise power thus determined are displayed on one and same display screen channel by channel.

  • Patent number: 7352713
    Abstract: A multiplexed signal quality display system, method, and program, and recorded medium where the program is recorded. The invention measures the quality of a multiplexed signal from a communication device wherein a band width to be used and the number of communication channels capable of being accommodated are determined by a diffusion code length, and channels to be used having the number of communication channels, which are determined by a diffusion code length, are decided in terms of a diffusion code number affixed to the type of the diffusion code, to effect communication while ensuring multi-channel communication lines in one and same band.

  • Patent number: 7162396
    Abstract: A measurement data displaying device includes a measurement data recording unit and charge displaying unit. The measurement data recording unit records a measurement subject channel, a spreading code length corresponding to the measurement subject channel and measurement data which is a code domain power or noise component power of the measurement subject channel. The chart displaying unit displays a chart having a constant width, and represents the measurement data in a display area whose position is determined by the measurement subject channel and the spreading code length, and which has a width corresponding to the spreading code length.

  • Patent number: 7020096
    Abstract: A display device, for displaying values of a physical quantity of multiple channels with different spreading code lengths, includes a channel storage for storing therein both the channels to be displayed and their respective spreading code lengths; a calculating unit for calculating the values of the physical quantity of the channels; a displaying unit for displaying the values of the physical quantity of the channels; and a threshold level comparator for determining a size relationship between the values of the physical quantity and a predetermined threshold level. The displaying unit displays the values of the physical quantity of the channels while changing a display condition in accordance with the size relationship between the values of the physical quantity and the threshold level.

  • Patent number: 7013243
    Abstract: Since a multiplexed signal quality display system according to the present invention is provided with a memory means which stores measurement results obtained by measuring electric powers of signals present in all of channels within a band used and a display means which specifies a channel where the presence of a signal is predicted and which reads and displays the measured value of the specified channel, it is possible to display the waveform quality of a channel which is determined by desired Walsh code and Walsh code length.

  • Publication number: 20040243357
    Abstract: Code domain powers in a plurality of kinds of code layers are simultaneously displayed. Display areas (312a, 312b, 312e, 312h, 312i, 312j) have widths corresponding to spreading code lengths W16, W8, W4 and are colored. Therefore even if measurement data such as the code domain powers in the code layer of plural kinds are simultaneously display on a bar chart, the code layers of the code domain powers can be distinguished.

  • Publication number: 20040004953
    Abstract: Display areas (W4, W8, W16, W32, W64, W128) have widths corresponding to the band widths determined according to the Walsh lengths and have heights representing the powers. Therefore, which display area corresponds to which Walsh length is known even though the powers of the measurement object channels having different Walsh lengths are combined and the result is displayed. The display areas are arranged in the Paley order, and therefore the display areas do not overlap with one another.
