What is a processor?
Refers to a system that accepts a program as input, prepares it for execution and executes the process defined with data to produce results. Can be a short term for a microprocessor or central processing unit (CPU) in computers.

What does OFDM stand for?
Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission techniques that ultilizes large numbers of carriesr spaced apart at slightly different frequencies. OFDM is used in many wireless application including Wi-Fi, digital radio and TV broadcasting in Europe and Japan and UWB. (Souce: EE Times)
