  Abstract

This paper proposes a novel blind adaptive algorithm for computing the weight vector of an antenna army system. The new technique utilizes a Generalized On-Off algorithm to obtain the weight vector maximizing the SINR(Signal to Interference plus Noise Ratio) of the received signal. It is observed that [he proposed algorithm generates a suboptimal weight vector with a linear computational load(O(6N+8)). From the various simulations, it is confirmed [hat, when the signal environment becomes adverse, e.g., low Processing Gain, and/or wide angular spread, the proposed algorithm outperform the conventional one in terms of the communication capacity by about 3 times. Applying the proposed algorithm to satellite tracking systems as well as IS2000 1X mobile communication system, we have found that both communication capacity and communication quality are significantly improved.
