A Hybrid Equalizer/ Rake Receiver

The data rate in conventional wireless communications systems is limited by multipath-induced inter-symbol interference (ISI). Modern systems, such as UMTS, employ measures to counter the effects of multipath propagation and fading. Two accepted methods are the Rake receiver and the LMMSE Equalizer. The Rake receiver is parti-cularly effective for propagation scenarios with large delay spread. While its computational complexity is typically less demanding in comparison to an equalizer, it is prone to interference caused by closely spaced paths. An equalizer, however, can handle such sce-narios perfectly well. In this work the strenghts and weaknesses of both techniques are compared. Subsequently, a hybrid equalizer/Rake receiver architecture and various approaches to combine the advan-tages of both receivers in a single system are presented. The per-formance of the respective algorithms is evaluated using bit-true simulation of a full-scale HSDPA baseband receiver developed at Infineon Technologies AG.
