We consider a chip-interleaved randomly spread DS-CDMA scheme employed in Wyner's infinite linear cell-array model with fiat fading. Focusing on the asymptotic setup, the per-cell spectral efficiencies of the optimum and linear MMSE joint multi-cell receivers are considered. Performance enhancement as compared to single-cell-site processing is demonstrated. The asymptotic behavior of the two receivers in extreme SNR regimes and in a high cell-load setup are analyzed as well. The impact of chip-interleaving vs. symbol-interleaving is also considered.
