ACQUISITION OF A WIRELESS REVERSE LINK SIGNAL AFFECTED BY DOPPLER FREQUENCY DRIFT |
摘要 |
<p>The invention relates to supporting an acquisition of a signal, wherein the signal comprises a sequence of complex valued samples, wherein the acquisition comprises an integration of the complex valued samples in subsequent integration intervals, and wherein the signal may be subject to a frequency drift. In order to enable an improved acquisition, a phase angle is estimated in the signal in a respective integration interval (step 504). The samples are adjusted based on the estimated phase angle in a respective integration interval (step 505). Only the adjusted samples from a plurality of integration intervals are then integrated (step 507, 508).</p> |
