... shaping and the second is correlation function shaping. The advantage of the discriminator function shaping technique is the reduced complexity of hardware and software. One of the benefits of correlation ... Thus, there is a tradeoff between the performance of multipath mitigation and computational load. Another focal point is that the proposed method (Figure 8) can b...
