“…This fact is particularly true when it comes to Signal Processing and Telecommunications, especially after the works by Pecora and Carroll [2] and Ott et al [3]. Chaos has appeared in different areas as digital and analog modulation, cryptography, pseudorandom sequences generation, watermarking, nonlinear adaptive filters, phase-locked loop networks, among others (see e.g., [4][5][6][7][8][9][10][11][12][13]). …”

“…Com o aparecimento frequente de novos desafios e aplicacões nessaárea, estudar novas técnicas e ideias que não se enquadram nos sistemas comerciais atuaiś e relevante como objeto de pesquisa. Como exemplos de aplicações em que recentemente vêm-se estudando o emprego de sinais caóticos podem-se citar: geração de sequências pseudoaleatórias para Acesso Múltiplo por Divisão de Código (CDMA -Code Division Multiple Access) (Rovatti et al, 2004), comunicaçõesópticas (Argyris et al, 2005), rede de satélites (Grzybowski et al, 2010) e modelagem de dispositivos (Monteiro et al, 2009), entre muitas outras.…”

In recent decades, many papers describing communication systems based on chaotic signals have been published. However, their performance under nonideal conditions needs further investigation. This work evaluates the performance in terms of Bit Error Rate (BER) of a binary communication system, based on Wu and Chua's synchronization method, when white gaussian noise is added to the transmitted signal. The simulations are performed using different maps. We numerically show that, if the coding function is adequately chosen, it is possible to obtain BER values close to the ones for conventional systems.

“…Applications of chaos ranging from digital and analog modulation to cryptography, pseudorandom sequences generation and watermarking have been proposed (Kennedy & Kolumban, 2000;Kennedy, Setti & Rovatti, 2000;Stavroulakis, 2005;Tsekeridou et al, 2001). Chaos has also been shown in connection to devices used in signal processing such as nonlinear adaptive filters and phase-locked loop networks (Endo & Chua, 1988;Harb & Harb, 2004;Monteiro et al, 2009;Tavazoei & Haeri, 2009). In particular, many recent works have described digital modulations using chaotic carriers (Kennedy & Kolumban, 2000;Kennedy, Setti & Rovatti, 2000;Kolumban et al, 1997;Kolumban, Kennedy & Chua, 1998;Lau & Tse, 2003) even though their performance proved below that of equivalent conventional systems under additive white gaussian noise channel (Kaddoum et al, 2009;Williams, 2001).…”
