Neste artigo, estudamos técnicas de macro/microdiversidade para aquisição de código de um sinal de espectro espalhado de seqüência direta em um sistema interno de comunicação por pacotes. No sistema discutido, a estação base possui diversas portas de rádio, cada uma com um conjunto de antenas, e o terminal também possui múltiplas antenas. O desempenho no uplink deste sistema é analisado sob sombreamento Lognormal e desvanecimento Rayleigh plano. Os resultados numéricos mostram grandes melhorias de desempenho pelas técnicas de diversidade propostas. Além disso, esclarece-se que o tempo médio de aquisição, que é frequentemente utilizado como medida de desempenho, não é adequado para sistemas de rádio de pacotes, uma vez que subestima o comprimento necessário do preâmbulo para a aquisição inicial do código.

Abstract: In this paper, we study macro/micro diversity techniques for code acquisition of a direct-sequence spread-spectrum signal in an indoor packet communication system. In the system discussed, the base station has several radio ports each with a cluster of antennas, and the terminal also has multiple antennas. The performance in the uplink of this system is analyzed under Lognormal shadowing and flat Rayleigh fading. The numerical results show great performance improvements by proposed diversity techniques. In addition, it is clarified that the mean acquisition time, which is often used as the measure of performance, is not suitable for packet radio systems as it underestimates the necessary preamble length for initial code acquisition.
