Abstract
In this paper we consider single-carrier with
frequency-domain equalization (SC-FDE) schemes where the
transmission bandwidth is above the symbol rate. To allow high
spectral efficiencies, several channels share the same bandwidth.
Since the co-channel interference (CCI) levels can be very high,
we propose iterative FDE receivers where we jointly detect all
users sharing the same channel. Our performance results show
that we can have excellent performances, even with several
users sharing the same channel. In fact, we can have the
maximum theoretical spectral efficiency even with signals that
have bandwidth substantially above the symbol rate
