Code division multiple access communication with pilot aided detection

摘要

Waveform estimating section 302 observes the amplitude and phase of pilot signals outputted from pilot despreading section 301, and estimates the amplitude, frequency and phase of the pilot signals having no interference. Sine wave generating section 303 generates pilot signals of sine wave of the estimated amplitude, frequency and phase. Coherent detecting section 305 corrects the phase shift of data signals outputted from data channel despreading section 304, using the generated pilot signals.
