Comparison of Multipath Error Elimination Techniques under Relatively Severe Multipath Environments

摘要

This paper presents comprehensive comparison of some of the multipath elimination techniques of the literature with the optimum deconvolution based technique proposed earlier. The comparison results of the paper are presented in a parameterized form wherein the key parameters include the receiver bandwidth, computational complexity of the algorithm, the number of multipaths present and their relative amplitudes, delays and carrier phase. Such a comparison shows that while for the case of a single secondary path, the performance of several algorithms may be close; the performance of the optimum deconvolution based algorithm can exceed the performance of some of the other algorithms, in terms of the residual multipath error, by orders of magnitude in a multipath environment comprising of multiple secondary paths.
