摘要: An input signal is a complex vector whose phase is a coherent measurement of the phase rotation occurring between two separated symbols of a received CDMA signal. A processing block (30) provides a first signal showing the magnitude and the sign of the imaginary part of the input signal, and a second signal showing the magnitude and sign of the real part of the input signal to an initialisation block (31). A quadrant determination block (32) examines the signs of the signals to determine the quadrant in which the phase of the input signal exists. A comparator block (33) determines if the magnitude of the first signal is greater than or equal to the magnitude of the second signal. If a negative determination is made, the magnitude of the first signal is doubled in a multiplication block (35) to form a multiplied signal, and a counter incremented, initially from zero. The comparator block (33) then determines if the multiplied signal is greater than or equal to the magnitude of the second signal. This continues until the multiplied signal is equal to or exceeds the magnitude of the second signal. Carried to an upscaling block (36) is the multiplied signal (or the first signal if there is no multiplied signal), the magnitude of the second signal and the count of the counter (M). The upscaling block (36) examines the multiplied signal (or the first signal) and determines an upscaling factor. The multiplied signal (or the first signal) is multiplied by the scaling factor, as is the second signal, and the upscaled signals are provided to an angle determination block (34). The phase error θe in degrees is estimated by the formula θe=45°/2M.

摘要: A radio receiver (30) comprises an ADC (13) including a clip counter. The power of digitised signals provided by the ADC (13) is estimated by a power estimator (31), and an ideal gain value is computed from the power so estimated by a gain computation device (32). Gain computation signals are fed to a gain control input of an amplifier (11) via an LPF (33). A saturation detector (34) is connected to a clip counter output of the ADC (13), and to a control input of the LPF (33). The saturation detector (34) is arranged when saturation of the ADC is detected to reduce the gain setting value by at least two steps, by which the gain of the amplifier is immediately reduced. A detector detects the Doppler frequency of signals received and accordingly determines the size of the drop in amplification which is effected when saturation of the ADC (13) is detected. The gain reduction may be 3 dB under very low Doppler shift conditions and 12 dB under very high Doppler shift conditions.
