PCT No. PCT/SE96/00694 Sec. 371 Date Dec. 11, 1997 Sec. 102(e) Date Dec. 11, 1997 PCT Filed May 30, 1996 PCT Pub. No. WO96/42143 PCT Pub. Date Dec. 27, 1996The present invention relates to an arrangement and a process for the demodulation of a received signal to a form suitable for decoding. A first element (4) is adapted to correlate at least one first signal with a predetermined training sequence for a first type of signal routine and to make at least one first qualitative measurement of the first signal. A second element (5) is adapted to process the second signal according to a second type of signal routine by correlating the second signal with a predetermined training sequence for a second type of signal routine, thereby making a first qualitative measurement of the second signal. The qualitative measurements of the said first and second signal are compared in a first means (6), which is adapted to select at least one signal for which the best value is obtained in the said qualitative measurement and to establish the type of signal routine corresponding to the best qualitative measurement. The arrangement finally comprises a demodulator (7) for the demodulation of at least one selected signal according to the established type of signal routine. |
