Abstract
We propose the application of the Levenberg-Marquardt (LM) algorithm to the code synchronization in multipath scenarios characterized by a large number of reflectors. The computational effort is kept at a reasonable level by assuming that the channel consists of a direct ray and a few reflectors despite the actual number of reflectors existing in the physical channel (in the paper we have considered a model with 3 reflected rays for the LM algorithm) . The proposed technique is highly parallelizable which permits to increase the speed of processing.
