OpenAirInterface Code Study and Interpretation

Important Notes:

• This expects to be a comprehensive walkthrought over the PHY layer implementation of OpenAirInterface project, it assumes the basic LTE protocol concepts are known.
• Although the OpenAirInterface have several applications, this study focus on the LTE eNodeB.
