The State as Part of the Republic

The State as Part of the Republic The main objective of this article is to analyze an ideal of civic life, the Republic, based on the form of the sovereign state. Historically, the convergence between Republic and sovereign state has been truncated by the former's commitment to the thesis of royal absolutism. However, as the democratic issue (translated in the values of equality and pluralism) was absorbed by sovereignism, such convergence became more plausible. As viewed in this article, the theoretical bridge of that passage is the concept of political representation. The issue is thus to show in what way a certain vision of the political form (that of the state) can fit into a theory of political representation that contemplates the above-mentioned values.

A regional multirnodulus algorithm for blind equalization of QAM signals: Introduction and steady-state analysis

It is well known that constant-modulus-based algorithms present a large mean-square error for high-order quadrature amplitude modulation (QAM) signals, which may damage the switching to decision-directed-based algorithms. In this paper, we introduce a regional multimodulus algorithm for blind equalization of QAM signals that performs similar to the supervised normalized least-mean-squares (NLMS) algorithm, independently of the QAM order. We find a theoretical relation between the coefficient vector of the proposed algorithm and the Wiener solution and also provide theoretical models for the steady-state excess mean-square error in a nonstationary environment. The proposed algorithm in conjunction with strategies to speed up its convergence and to avoid divergence can bypass the switching mechanism between the blind mode and the decision-directed mode.
