Summary (two sentences) (2pts):
The purpose of this lab was to use Tutor TIMS to implement and learn about Orthogonal Frequency Division Multiplexing(OFDM). In addidion, Tutor TIMS was used to generate an OFDM signal.
Introduce the student to the underlying theory of operation of Orthogonal Frequency Division Multiplexing (OFDM).
Learn to use TIMS modules to implement an OFDM generator scheme.
Generate and analyze OFDM waveforms.

OFDM (Orthogonal Frequency Division Multiplexing) is a combination of modulation and multiplexing, and more specifically, is a special case of Frequency Division Multiplexing (FDM), as the name implies.
A single main data stream is split into many lower rate data streams (multiplexing). Each of these streams is then individually modulated onto a separate sub-carrier (modulation) and finally recombined into a single composite OFDM signal to be transmitted.
The addition of a cyclic prefix is also an important part of OFDM, however, this feature will be discussed but not implemented in this introductory experiment. The coding blocks will not be covered in detail within this experiment.
