power amplifiers (pas) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. although most existing architectures assume that the pa has a memoryless nonlinearity, memory effects of the pas in many applications ,such as wideband code-division multiple access (wcdma) or orthogonal frequency-division multiplexing (ofdm), can no longer b...

A/~ruci-The capacity region of the discrete memoryless interference channel with strong interference is established.

Abstract In this paper, the stabilization mechanism, dual-channel switching is investigated for a class of discrete-time networked control systems with parameter uncertainties and cyber attacks. A novel mechanism proposed against denial-of-service attacks achieve system asymptotic stability. The event-triggered scheme considered to unnecessary data communications. Based on this, memory-based pu...

This paper analyzes the robust feedback stability of a single-input-single-output stable linear time-invariant (LTI) system against three different classes nonlinear systems using Zames–Falb multipliers. The contribution is threefold. Firstly, we identify class uncertain over which equivalent to existence an appropriate multiplier. Secondly, when restricted be static (a.k.a. memoryless), such c...

Several nonlinear adaptive techniques have been proposed for modelling nonlinear channels with memory. These techniques include Volterra series, wavelet networks, neural networks, etc. See [11, 6] for a review. For example, adaptive Volterra series have been applied in [1] for modelling digital satellite channels. These Volterra models do not characterize each element of the channel. They provi...

In a wireless cellular system the equalizer can be regarded as an inner decoder in the serially concatenated convolutional coding systems. In the proposed system, ui ∈ {0, 1} is the input symbol and si is the state in the trellis diagram. yi is the output of 1/n convolutional encoder and ri is the output of the memoryless channel. Let Ll be the set of all possible information sequences of lengt...
