V. 1.0 - 22.09.2003

Copyright (C) 09/2003 by Howard Fuhs

In this lecture I refer to several different modulation types (analog as well as digital). I want to give a brief overview about the short cuts of modulation types I will mention and the meaning of the short cuts.

AMAmplitude Modulation
FMFrequency Modulation
PCMPulse Code Modulation
PAMPulse Amplitude Modulation
FDMAFrequency Division Multiple Access
TDMATime Division Multiple Access
CDMACode Division Multiple Access
TDMTime Division Multiplexing
PSKPhase Key Shifting
QPSKQuaternary Phase Key Shifting
SCPCSingle Channel Per Carrier
FECForward Error Coding
Spread Spectrum

I invite your suggestions for revising this document. I plan to review and revise this document as the need arises.
