Principles of Digital Modulation - Berk

2 Principles of Digital Modulation: Outline of Lectures l Introduction to digital modulation l Relevant Modulation Schemes (QPSK, GMSK, M-Ary Schemes) l Coherent and Differential Reception l The impact of the mobile channel on digital modulation – noise and interference – random FM (narrowband fading) – intersymbol interference (wideband fading)

Peak E ciency Power Added E ciency (PAE) is a popular metric. P out is the output power, P in is the input power, and P dc is the DC power consumption of the PA For high power gain systems (G p), the e ciency approaches the drain drain e ciency ( d), or for a BJT, the \collector" e ciency, or simply the e ciency of the last stage

GAUSSIAN MINIMUM SHIFT KEYING (GMSK) - Rutvij C

INTRODUCTION TO GMSK |Gaussian Minimum Shift Keying (GMSK) is a form of continuous-phase FSK in which the phase change is changed between symbols to provide a constant envelope. Consequently it is a popular alternative to
