Abstract: The objective of this paper is to find an optimum correlator configuration that is capable of achieving the best possible multipath mitigation performance for an MBOC modulated signal. A new code multipath mitigation technique will be presented. The followed approach is the optimization of the shape of the code discriminator function, on account of the definition of an optimum S-curve. A fundamental aspect of the Scurve optimization will be to search for the right compromise between bandwidth of the pre-correlation filter and the required resolution of the correlators. The method to calculate the weights of the correlators to obtain an optimum S-curve will be equally shown. The implementation of the optimum discriminator is illustrated and the results of several simulations are presented. Additionally, the obtained performance will be assessed by means of multipath envelopes. To conclude, a comparison of multipath performance figures using a statistical channel model is given.
