摘要

"Digital oscillator, the base station in a radio network communication, wireless terminal, and the process to generate a first signal and a second digital sine signal digital sine wave.The present invention is related to a digital oscillator (400) for use in a radio receiver (110). The oscillator includes a signal generator (401), generating a digital sinusoidal signal (S43).The digital sinusoidal signal (S43) feeds the middle phase shift (402) being separated from the signal generator (401).The phase shift (402) derived from the digital sinusoidal signal (S43) a first pair of sine signals to digital (S44 - S45) having a phase difference corresponding to at least one ETAPThe sampling.The first pair of sine signals to digital (S44, S45) feeds the means of ortogonalizau00e7u00e3o (403) which produces a pair of orthogonal digital sine signals (S41,S42) forming linear combinations of the first pair of sine signals to digital (S44, S45).
