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 mitigate MCI may be via properly designing...
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 orthogonality in multipath channels. Moreover, the analytical results show that the proposed sequence can greatly reduce the multi-cell interference (MCI) induced by carrier...
This paper presents the modeling and estimation of state of charge (SoC) for Li-ion batteries using ANFIS architecture. The system consists of two phases of operation. The phase 1 is the SoC modeling process. The phase 2 is the real-time estimation process. Firstly, on the phase-1 operation, a brand-new Li-ion battery is used for a completely discharge cycle which consists of 355 cycles of discharge/charge...
In the study of location partial discharge in transformer based on the UHF method, in order to accurately locate partial discharge source, precisely achieving time delay of different signals which are received by different UHF sensors and radiated from the same partial discharge source is essential. Three methods of time delay estimation are introduced and compared, including the initial peak, the...
