This LTE Air Interface Techniques Training course will undertake an in-depth study of the LTE air interface.  It will begin with a discussion of the radio channel environment and the related RF propagation issues to help you understand the problems that OFDM/MIMO solves. This is followed by a discussion of the modulation principles along with a detailed look at the LTE physical layer structure as it complements the modulation and MIMO channels. The transmitter and receiver parameters and techniques, based on the 3GPP specifications, are then presented.  We conclude with a discussion of the physical layer procedures with an emphasis on channel quality and random access techniques.
