Principles of Digital Modulation - Berk
1 Principles of Digital ModulationDr Mike Research LabToshiba Research Europe Limited2 Principles of Digital Modulation : Outline of LectureslIntroduction to Digital modulationlRelevant Modulation Schemes (QPSK, GMSK, M-Ary Schemes)lCoherent and Differential ReceptionlThe impact of the mobile channel on Digital Modulation noise and interference random FM (narrowband fading) intersymbolinterference (wideband fading)3 Digital ModulationBasics4 Digital Modulation BasicslThe bit rate defines the rate at which information is passed. lThe baud (or signalling)ratedefines the number of symbols per second. Each symbol represents nbits, and has Msignal states, where M = 2n.
9 Modulation - QPSK lQuadrature Phase Shift Keying is effectively two independent BPSK systems (I and Q), and therefore exhibits the same performance but twice the bandwidth efficiency. lQuadrature Phase Shift Keying can be filtered using raised cosine filters to achieve excellent out of band suppression.
