Abstract: Methods and apparatus are disclosed for data packetizing in an orthogonal frequency division multiplexing (OFDM) system. In order to improve transmission efficiency, the present invention uses independent packet and OFDDM block boundaries. Therefore, a packet is allowed to go across the OFDM block boundary and packed into two OFDM blocks. To indicate the start of each packet, a Frame Delimiter (FD) with a predefined format is inserted in front of each packet. The predefined format of the FD can be a predefined bit pattern or modulation points of modulation constellation. Idle data can also be inserted into OFDM blocks when no packet is ready. When data of one or more packets and idle data contain the predefined bit pattern of the FD, the data are modified to avoid generating the pre-defined bit pattern.
