Abstract  Abstract

Techniques for transmitting information using cyclically shifted sequences are described. In one design first and second sequences may be generated by cyclically shifting a base sequence by first and second amounts respectively. The base sequence may be a CAZAC sequence a PN sequence or some other sequence having good correlation properties. The cyclic shifts for the first and second sequences may be determined based on a hopping pattern. A first modulated sequence may be generated based on the first sequence and a first modulation symbol and may be sent in a first time interval. A second modulated sequence may be generated based on the second sequence and a second modulation symbol and may be sent in a second time interval. Each modulated sequence may be sent on K consecutive subcarriers using localized frequency division multiplexing (LFDM).
