Thevenin's model having a RC network characterizing the battery polarization is used for SOC determination. Reverse current method is proposed to decrease the polarization elimination time. And the polarization voltage of the battery model is identified using the nonlinear least square technique. A maximum available capacity based SOC determination method considering the SOC limit of each cell for...
Unified Modeling Language (UML) provided effective means for aspect-oriented modeling, among which UML state machine was designed to model for the dynamic behavior of the system. UML state machine, however, failed to explicitly support the modeling of a crosscutting feature. The paper, based on UML extension methods, firstly set up state class in supported aspect from level of state machine meta-model,...
The differential constant modulus (DCMA) multiuser detection can obtain higher steady-state decorrelating performance than the conventional linear algorithm under high SNR condition similar as the constant modulus algorithm (CMA). Unlike CMA criterion, DCMA has single global minimum which leads to the convergence independent from the amplitudes of received signal. However, the closed-form analysis...
The use of multiple entropy models for Huffman or arithmetic coding is widely used to improve the compression efficiency of many algorithms when the source probability distribution varies. However, the use of multiple entropy models increases the memory requirements of both the encoder and decoder significantly. In this paper, we present an algorithm which maintains almost all of the compression gains...
The estimation of receiving impulse template can be simplified by the transmitted reference (TR) signaling scheme in ultra-wideband communication. However, in multiuser environment, the TR scheme would be severely interfered for its non-coherence. By modulating the transmitted-reference with a pseudo-random code, we propose an analog LMS detection based on minimum mean-square error criterion to suppress...
