DOI: 10.1007/s10476-020-0038-6
Abstract: The well-known stationary phase formula gives us a way to find asymptotics of oscillating integrals so long as the symbol is regular enough (in comparison to the large parameter controlling the oscillation). However in a… read more here.

DOI: 10.1007/s11277-019-06220-5
Abstract: Inter-symbol interference (ISI) causes many errors in modulated symbols, when they are transmitted through band-limited channels. According to the multipath delay profile of the channel, the modulated symbol may disperse over more than one symbol… read more here.
