—We propose a training sequence that can be used at the handshaking stage for multi-cell networks. The proposed sequence is theoretically proved to enjoy several nice properties including constant amplitude, zero autocorrelation, and orthog-onality in multipath channels. Moreover, the analytical results show that the proposed sequence can greatly reduce the… (More)
improves PAPR while it only slightly degrades bit error rate.
In this paper, we propose an algorithm for estimating the carrier frequency offset (CFO) in OFDM-based multi-cell networks. In 3GPP-LTE single-cell systems, the CFO can be estimated by applying the Schmidl algorithm. However, multi-cell interference (MCI) is induced in multi-cell environments; as a result the MCI degrades estimate accuracy. One solution to… (More)
