When the use of mobile devices is soaring, the demand for higher data rates over wireless networks is continuously increasing. To meet the demand, one of the obvious solutions is to increase the bandwidth of the transmission frequency band. However, no matter how much you are willing to pay for the spectrum, you can no longer easily obtain a large contiguous bandwidth because most spectrum bands have...
A dual-band bandpass filter using a transversal-interference multimode resonator is proposed. The resonator is composed of a flatten ring resonator attached with two open-circuited stubs. By properly selecting the connecting position between the stubs and a ring, the two pairs of resonant modes can be grouped to make up the dual-passband response, and they can be further separated with virtue of two...
This paper presents the design of compact low-loss bandpass filter using the proposed hybrid resonator. The hybrid resonator is composed of a microstrip line and a short-circuit coaxial line. The proposed hybrid resonator configuration provides the advantages such as high Q-factor, small size, light weight, integration with other printed circuits such as power amplifier, low noise amplifier, mixer...
This paper proposes a recurrent fuzzy neural network (RFNN) for speech detection. The underlying notion of the proposed RFNN is to consider minimum classification error (MCE) and minimum training error (MTE). The weights of RFNN are updated by maximizing the discrimination among different classes in MCE. Besides, the parameter learning adopts the gradient descent method to reduce the cost function...
This paper proposes the chip design of memory-architecture-based minimum-classification-error (MCE). The major contribution is of this MCE chip is to increase the discriminative capability rather than to fit the distribution of data in the application of classification problems. It includes matrix-function, exponent, logarithm, sigmoid function, and square-root. To implement MCE, UMC 90nm standard...
With the explosive development of Internet, Peer-to-Peer systems are increasingly capturing the attention of researchers and practitioners. Due to remarkable differences of P2P application backgrounds, we divide the P2P system into P2P platform layer and P2P application layer. This paper introduces the key technologies of a P2P platform and emphasizes on the underlying technologies such as Communication,...
