摘要

The performance of a multiuser OFDM transceiver, proposed by authors In [10] and called the preceded multiuser OFDM (PMU-OFDM) In this work, with time asynchronous access Is Investigated. We show that the multiaccess Interference (MAI) due to time asynchronous access can be reduced to a negligible amount by adopting a proper preceder that uses M/2 symmetric or M/2 anti-symmetric codewords of the M Hadamard-Walsh codes for the preceding task. The PMU-OFDM transceiver with the same preceder was shown to have approximately MAI-free property In a frequency asynchronous environment [11]. Here, we analyze the the approximately MAIfree property of the PMU-OFDM system with respect to time asynchronlsm. Finally, computer simulation Is performed to confirm the derived property.
