A method and rake receiver for phasor estimation in communication systems |
摘要 |
<p>The invention relates to a channel estimation algorithm is proposed for a RAKE receiver for CDMA communication systems operating in the downlink of a mobile communication scenario yielding an improved phasor estimation. Received signals are distributed to a plurality of receiver fingers of a RAKE receiver. Each receiver finger i is assigned to a signal path of the transmitted signal which is subject to phase shift and power dissipation due to reflection, diffraction and scattering. According to the invention the approach partly cancels multipath/multiuser interference and offers the advantage of being able to cope with physically closely spaced multipaths.</p> |
