A Multi-User Receiver for PUCCH LTE FORMAT 1 in Non-Cooperative Multi-Cell Architectures

In this paper, the authors propose a new multi-user receiver processing for PUCCH LTE that counteracts the ICI in a non-cooperative multi-cell architecture. Using the fact that the received signal in PUCCH signaling follows a constrained tensor model, a multi-user receiver based on an iterative joint channel/code estimation and symbol detection is proposed. The interest in such a challenging setting relies on the overhead reduction among neighboring cells. Simulation results show remarkable performance gains of the proposed receiver compared to the conventional time-frequency de-correlator based receiver under the same conditions. They also show a performance comparison with the cooperative version of such a tensor receiver.
