    摘要： A method for determining a signal propagation time mismatch in a modulator comprises generating a predetermined signal shape of a amplitude component of a radio frequency signal generating one or more predetermined conditions in a frequency component of the radio frequency signal at a first time interval relative to the predetermined signal shape and detecting the one or more predetermined conditions in the frequency component at a second time interval. The method further includes determining the amplitude component at the second time interval and calculating a signal propagation time mismatch value based on the signal shape of the amplitude component, on the first time interval and the second time interval.

    摘要： The invention relates to improvements of spread spectrum GMSK (Gaussian Minimum Shift Keying) signals, particularly to method for generating a spread spectrum Gaussian Minimum Shift Keying, GMSK, signal comprising obtaining a sequence D(t) of data symbols for a data channel, obtaining at least one first spread spectrum code comprising a first sequence C D (t) of spread spectrum chips for the data channel, obtaining at least one second spread spectrum code comprising a second sequence C P (t) of spread spectrum chips for a pilot channel, generating a sequence r(t) of pre-modulation chips by combining the sequence D(t) of data symbols for the data channel with the spread spectrum chips of the first sequence C D (t) of the at least one first spread spectrum code and data symbols for the pilot channel with the spread spectrum chips of the second sequence C P (t) of the at least one second spread spectrum code to a combined sequence of chips, assigning the chips of the combined sequence of chips to the transmission channels In-Phase I and Quadrature Q of the spread spectrum GMSK signal so that not more than two consecutive pre-modulation chips generated with the same spread spectrum code are transmitted in the same transmission channel I or Q, and performing GMSK modulation g(t) using the sequence of pre-modulation chips to generate a spread spectrum GMSK signal s(t).
