| Summary: | It is well known that wireless sensor network become more and more popular in modern communication systems. The DOA estimating theory is used to renew system topology and routing method of the whole network which is of great important in military communication. In this work, we raised an enhanced DOA (Direction of Arrival) estimating method which is used in wireless military sensor networks with uniform circular array. The array based sensor network is widely used in battlefield communication or emergency communication. Compared with traditional DOA estimating method such as ESPRIT and MUSIC, our new method has better performance but lower calculation consumption. From the simulation results, we can also infer that our method has better performance in Block Error Rate (BER) and lower mean-square error when the SINR of the received signal is poor, which is meaningful for establishing and maintaining a stable and perfect battlefield communication.
