METHOD AND RECEIVER FOR REDUCING THE EFFECT OF MULTIPATH PROPAGATION

摘要

The invention relates to a method for reducing the effect of multipath propagation in a receiver (1) in which a code-modulated spread spectrum signal is received. In the method, at least one reference code (r(x)) corresponding to a code used in modulation is used to form at least two reference signals with different phases. Correlation between a received signal and each reference signal is performed to form correlation values. The method also comprises the steps of forming a divider function and performing at least a deconvolution step, in which a first time-to-frequency transformation is performed on the corelation results to form first transform results, and the first transform results are divided by the values of the divider function to form a division result. The invention also relates to a receiver (1) for receiving a code modulated spread spectrum signal, and an electronic device (24) comprising at least a positioning receiver (1) with count (2) for receiving a code modulated spread spectrum signal.
