Delay-induced scattering with phase randomization and partitioned frequency hopping

摘要

A method includes partitioning a set of hopping carrier frequencies into disjoint sets including a first set and a second set such that a frequency correlation between a first hopping carrier frequency of the first set and a second hopping carrier frequency of the second set is approximately zero. The method also includes generating at least one copy of a signal, which includes a plurality of time division multiple access (TMDA) frames. The at least one copy of the signal has a fixed delay and a random phase relative to the signal. The method further includes transmitting the signal and the at least one copy of the signal using selected hopping carrier frequencies from the first and second sets such that a frame is sent using the first hopping carrier frequency from the first set and an adjacent second frame is sent using the second hopping carrier frequency from the second set.
