摘要： A receiving apparatus eliminating the need for performing at all times a function provided for a mode that is most susceptible to deterioration in accuracy in adaptive modulation communication. In a spread spectrum communication system according to the present invention, a control unit reads a demodulating method from a control signal specifying the demodulating method, and on the basis of the read demodulating method, the control unit controls a sampling rate of an A/D conversion unit and a despreading unit, a number of pilot symbols used by a propagation path estimating unit, and a number of pilot symbols despread by the despreading unit. Thereby, when the demodulating method is other than 64-QAM, the sampling rate and the like adjusted to QPSK or 16-QAM can be set.

摘要： Disclosed is a method and an apparatus for controlling transmission electric power capable of minimizing a decrease in the amount of maximum transmission electric power without degrading an adjacent channel leakage power ratio when code-multiplexing additional control information with data and main control information. A mobile device checks values of gain factors βd and βc when performing code multiplexing to transmit signals from channels DPDCH to transmit data, DPCCH to transmit main control information, and HS-DPCCH to transmit additional control information. A maximum transmission electric power is decreased at a plurality of levels based on the check result and a ratio (Δhs) between the gain factors βc and βhs. It may be preferable to check the presence or absence of transmission data instead of the gain factor βd. In this case, when no transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on Δhs. When transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on the gain factor βc and Δhs.

摘要： A method and apparatus is disclosed by which, in communication wherein a pilot channel for a pilot signal and an estimation object channel have different bandwidths, the channel quality of the estimation object channel can be estimated accurately based on the pilot signal. A despreading section separates data of the object channel and the pilot signal of the pilot channel. A channel estimation section determines a channel estimation value based on the pilot signal. A pilot channel quality estimation section produces signal and noise levels of the pilot channel based on the channel estimation value and the pilot signal. A low frequency noise component estimation section produces a low frequency component of pilot signal noise. A data channel quality conversion section determines the data channel quality based on the outputs of the pilot channel quality estimation section and the low frequency noise component estimation section.
