signal, phase shift keying (PSK) is produced. If both the amplitude and the phase are varied proportional to the information signal, quadrature amplitude modulation (QAM) results. ASK, FSK, PSK, and QAM are all forms of digital modulation: () Figure shows a simplified block diagram for a digital modulation :// channels are presented in Sections 6 and 7. Section 8 proposes a blind identiﬁca-tion algorithm for the estimation of sparse channels.
