Um esquema de aquisição sequencial modificado é proposto nesta carta para evitar as altas probabilidades de erro significativas (alarme falso e probabilidades ausentes) que ocorrem com o esquema de aquisição sequencial convencional em sistemas de espectro espalhado de sequência direta enquanto um deslocamento de alta frequência está presente. Um novo estimador de Ek/N0 também foi projetado para resolver efetivamente os problemas causados pelos efeitos de desvanecimento do canal. Extensos resultados de simulação computacional indicaram que a técnica proposta pode atingir as baixas probabilidades de erro desejadas e, além disso, seu desempenho é muito próximo daquele da estimativa de canal perfeita.

Abstract: A modified sequential acquisition scheme is proposed in this letter to avoid the significant high error probabilities (false alarm and missing probabilities) occurring with the conventional sequential acquisition scheme in direct-sequence spread-spectrum systems while a high frequency offset is present. A new estimator of Ek/N0 is also designed to effectively solve the problems caused by the channel fading effects. Extensive computer simulation results have indicated that the proposed technique can achieve the desired low error probabilities, and furthermore its performance is very close to that with the perfect channel estimation.
