Abstract

In this contribution, a single carrier frequency domain equalization (SCFDE) transmission using space-time- spreading (STS) for multiuser broadband wireless frequency selective fading channel is investigated. Each user equipped with two transmit antennas is assigned two orthogonal data spreading codes and a third pilot spreading code to facilitate channel estimation. We propose a joint channel estimation and multiuser detection receiver. We show that the proposed scheme is multiuser interference (MUI) free and that increasing the number of users in the system does not affect the bit error-rate performance. Our study shows that by appropriately choosing the system parameters, we can achieve a fourth-order diversity gain without bandwidth expansion with one receive antenna at the base station. Moreover, because a single carrier transmission is used, the peak-to-average power ratio (PAPR) is greatly reduced which makes the technique a promising uplink transmission scheme. © 2008 IEEE.
