Abstract:
Dynamic Hopset Allocation Frequency Hopping OFDMA (DHA FH OFDMA) has been initially
proposed in [1]. Since then a number of modifications has been considered. Noncoherent DHA FH
OFDMA with threshold reception seems the most promising one since it is much less vulnerable to
multitone jamming than the conventional FH OFDMA. However in [1] it has been assumed that all
the signals from all users have the same power at the receiver side and the received signal is affected
only by multiple access interference (i.e. signals transmitted by the other users) and additive white
Gaussian noise.
