Abstract
Methods, receivers and transmitters all adapted to assist in the performance of layer 2 frame delineation are provided which are applicable in the context of OFDM, and also applicable to any layer 1 design facilitating high data rate transmission. Advantageously, the invention allows the identification of where a layer 2 frame begins notwithstanding the fact that the previous layer 2 header, which would normally be used to identify the location of the next layer 2 frame, has been received in error. As a consequence, rather than discarding considerable quantities of data after an erroneous header, for example all data until a super-frame boundary, layer 2 frames can be correctly received staring with the next header received in a non-erroneous layer 1 frame.
