This paper considers the uplink transmission
in BS (Base Station) cooperation schemes where users in
adjacent cells share the same physical channel and the
signals received by each BS are sent to a CPU (Central
Processing Unit) that combines the different received
signals associated to a given user and/or performs the
user separation. The signals are modulated through SC
(Single-Carrier) schemes combined with FDE (Frequency-
Domain Equalization) techniques and with iterative
frequency-domain receivers based on the IB-DFE concept
(Iterative Block Decision Feedback Equalization). Our
performance results show performance results close to
the MFB (Matched Filter Bound), where the proposed
receivers allow enhancement in macro-diversity gains
as well as an efficient user separation, making these
techniques an excellent choice for the uplink transmission
in future broadband wireless systems employing BS
cooperation schemes.
