Este artigo discute o emprego de arranjo de antenas adaptativas na estação base de um sistema CDMA Multi Processing Gain (MPG). É mostrado que o arranjo de antenas adaptativas com o esquema de controle de peso baseado no sinal antes do procedimento de desprendimento não aumenta, mas até diminui o desempenho do que com uma antena omnidirecional, e a causa desta grave degradação de desempenho é revelada. Em seguida é mostrado que o desempenho com o esquema de controle de peso baseado no sinal após o procedimento de desprendimento é sempre melhor do que com uma antena omnidirecional. Além disso, são mencionadas as possibilidades de melhoria de desempenho pela combinação de antenas de arranjo adaptativo e técnicas de cancelamento de interferência.

Abstract: This paper discusses the employment of adaptive array antennas at the base station of a Multi Processing Gain (MPG) CDMA system. It is shown that the adaptive array antenna with the weight control scheme based on the signal before despreading procedure does not increase but even decreases the performance than that with an omni-directional antenna, and the cause of this serious performance degradation is revealed. Then it is shown that the performance with the weight control scheme based on the signal after despreading procedure is always better than that with an omni-directional antenna. Furthermore, the possibilities of performance improvement by the combination of adaptive array antenna and interference cancellation techniques are mentioned.
