The performance of multi-cell channel estimation based on virtual pilot sequences and partial correlation has been investigated. The scheme uses a specific cell planning for the sequences by which pilots of different sites are scrambled. Using block-orthogonal sequences, the less mobile users are the more channels, i.e., interferers can be estimated with sufficiently low mean square error. It is shown that multi-cell estimation clearly outperforms the covariance estimator required for interference rejection combining at the terminal. Also it is shown that the suggested scheme achieves a mean square error below - 19 dB for the five strongest downlink signals received by a terminal.
