METHOD AND ARRANGEMENT IN WIRELESS COMMUNICATION NETWORKS USING RELAYING

摘要

A wireless communication system with relaying to enhance performance provides artificial frequency selectivity and spatial diversity by introducing delay diversity. A OFDM chunk is subjected to a 2D cyclic prefix by pre-appending to a representation of the chunk the last column of the representation. The last row of the pre-appended chunk is copied to the top of the augmented chunk forming an augmented chunk.
