摘要： According to the present invention, the inputted spectrum diffusion signal is orthogonal-transformed (16), and then, the common mode output Zre and the orthogonal mode output Zim are respectively AD-transformed (23, 24). Zre and Zim are respectively inputted to series connections of delay units respectively having a sampling period, and the corresponding delayed outputs are complex-multiplied (20i). Each output is N-points-complex-Fast-Fourier-transformed, and the absolute value of the each coefficient is squared. The squared absolute value is two-dimensionally displayed by setting a horizontal axis as a frequency axis and a longitudinal axis as a time axis (32). Then, a carrier wave frequency error is obtained from the maximum peak of the frequency, and a timing phase is obtained from the time.

摘要： The present invention offers a method and apparatus for measuring the waveform quality of a CDMA signal with increased accuracy. A baseband digital measuring signal Z(k) from a quadrature transform/complementary filter 22 is applied to a demodulating part 25, wherein it is demodulated by a PN code of a pilot signal to detect a bit train and an amplitude a'.sub.i. An ideal signal R.sub.i is generated from the bit train, the amplitude a'.sub.i and the PN code. At the same time, auxiliary data A, B, C, H and I, which are used to solve approximate simultaneous equations for computing parameters that minimize the square of the difference between the ideal signal R.sub.i and the measuring signal Z(k), are generated in an ideal signal/auxiliary data generating part 26. The thus obtained auxiliary data and the measuring signal Z(k) are used to solve the simultaneous equations to estimate the parameters in a parameter estimating part 27. The parameters are optimized by repeatedly correcting the measuring signal Z(k), the ideal signal R.sub.i and the auxiliary data A, B, C, H, I based on-the estimated parameters and estimating the parameters based on the corrected data. When the parameters are optimized, the power coefficient .rho..sub.i is computed using the optimized measuring signal Z(k) and the PN code.

摘要： When a signal having two or more frequency components is fed to a circuit to be measured, a phase of the signal output from the circuit to be measured is measured. A phase measurement device measures an output when an input signal having two input frequency components ω10 and ω20 is fed to an amplifier (circuit to be measured). The phase measurement device includes an orthogonal converter that subjects the output of the amplifier to an orthogonal conversion using an average frequency ω0, which is an average of ω10 and ω20. A phase acquisitioner acquires phases θ1 and θ2 of the input frequency components in the output of the orthogonal converter and a phase θ3 of a distortion component. A match time/phase measurer measures a match time Δt during which phase θ1 is matched with phase θ2, and measures phase θ1 (Δt) during that time. A distortion component phase measurer measures phase θ3 (Δt) of the distortion component in the match time Δt. A display then displays θ1 (Δt) and θ3 (Δt).
