Abstract

In this paper, the issue of channel estimation in Single Carrier Frequency Domain Equalization (SC-FDE) uplink Space Division Multiple Access (SDMA) systems in the presence of intra and inter-cell interference is addressed. It is shown that in such an interference-prone system, a combination of orthogonal pilots, spatial processing and Iterative Channel Estimation (ICE) is effective. Adaptive Iterative Block Soft Decision based Feedback Equalizer (IBDFE) with Parallel Interference Cancellation (PIC) assisted Decision Feedback Iterative Channel Estimation is employed. It is shown that such a combination is a promising way to suppress uplink inter-user interference.
