摘要
A communication device includes a communication interface and a processor configured to generate, transmit, receive, and process signals. The communication device generates orthogonal frequency division multiplexing (OFDM) frame(s) that include a two-dimensional (2D) start burst marker (BM), a data payload, and a 2D stop BM, and transmits the OFDM frame(s) to another communication device. Alternatively, the communication device receives OFDM frame(s) that include a 2D start BM and a 2D stop BM, and then identifies a data payload within those OFDM frame(s) based on the 2D start burst marker and a 2D stop BM. The 2D start and stop BMs are based on predetermined sequences having particular formats based on corresponding 2D sub-carrier and OFDM/A frame based structure. A receiver communication device then detects the 2D start BM and 2D stop BM within the received OFDM frame(s) based on knowledge of these predetermined sequences and particular formats.
