Abstract :
The optimum set of modulation filters for multicarrier modulation on two-ray channels is derived in closed form. These filters are shown to be sinusoidal even for a finite number of carriers. The proposed modulation scheme optimizes the performance of two-ray channels corrupted by additive white Gaussian noise without incurring the data rate loss associated with FFT-based multicarrier transceivers. The case of multiple-ray channels is also considered.<>
