Description

The issues of frequency offset and channel estimation are considered for the downlink of coordinated multiple input
multiple-output orthogonal frequency-division multiplexing systems. Multiple carrier frequency offsets exist in this coordinated system. Without implementing an appropriate compensation for these offsets, both inter-carrier and inter-cell interferenc will degrade the system performance. Here, we should adopt a parallel interference cancelation strategy to iteratively mitigate intercell interference, and propose a frequency offset estimator,approximated by a Hadamard product and a Taylor series
expansion, to eliminate the inter-carrier interference. The scheme is significantly less complex than existing methods. Furthermore, the channel estimator is robust to frequency offsets and performs comparably well to these conventional approaches.
