<p>The invention relates to a method for incoherent demodulation of orthogonally coded DSSS signals modulated with MSK or similar modulation types. The data signals are retrieved by splitting the received signal into two parts where the carrier is down converted to baseband by a signal (S12, S22) which is not adapted to the phase of the carrier, whereafter the down converted signals pass a correlator (13, 14), quadrature devices (15, 16) and adding devices (17, 18) and finally a discriminator (19) which always chooses the highest correlation peak as output signal (S30).</p> |
