Abstract
This paper shows that a CCRW receiver with a single window of variable width effectively mitigates multipath and ambiguity, on Global Navigation Satellite Systems (GNSS) that employ Multiplexed Binary Offset Carrier (MBOC) modulations. The following alternatives were tested for setting the widths of the W and BRW windows, namely: both fixed, W variable and BRW fixed, W fixed and BRW variable, both variable and W variable (without using BRW). Although all receivers that involved one or more windows with variable width were capable of eliminating multipath and ambiguity, the last alternative was selected because it corresponds to the most simple configuration among the cases tested. Besides, it is computationally simple, and thus it is completely suitable for implementation in low cost GNSS receivers.
