Abstract  Abstract

One or more preambles are inserted into frames of Orthogonal Frequency Multiplexing (OFDM)-Multiple Input Multiple Output (MIMO) signals. The preamble is received by the antennas of a receiver decoded and compared to known values to provide synchronization framing channels estimation offsets and other corrections to the transmitted signal.
