An Algorithm for Software Integrated Smart Antennas in TD-SCDMA Systems
Ze‐Ming Xie · Telecommunication Engineering · 2007
A scheme for software antennas integrating the multi-beam antenna and the LMS adaptive antenna based on SINR criteria is given.By using the switching combination,the proposed software antenna connects its output to one of the two antennas with higher SINR,realizing the algorithm diversity.The simulation results obtained in TD-SCDMA dynamic model show that the bit error rate(BER)performance of the proposed software antenna is better than that of the multi-beam antenna or the LMS adaptive antenna.The dynamic shifting of the distance between users and the base and the changing of the user's direction of wave arrival,as well as the influence of the power control and the synchronizing,are considered in the simulation.
