ABSTRACT:
A wireless communication system uses relaying to enhance performance. Artificial frequency selectivity and spatial diversity are provided by introducing delay diversity. A transformed OFDM chunk is subjected to a 2D cyclic prefix by pre-appending to a representation of the chunk the last column of the representation and by copying a number of the last rows of the pre-appended chunk to the top of the representation thereby forming an augmented OFDM chunk.
