E-mail: Abstract The paper introduces the fundamentals of multiplexing and multiple access (MA) technologies for mobile communication systems. We first provide a simple formulization of MA schemes through mathematical expression that is based on CDMA. Using the expression, three concepts of MA are introduced. We also introduce two important performance measures: signal to interference-and-noise ratio (SNIR) and spectral efficiency. Based on the discussion on MA, we then introduce multiplexing techniques.
